Discover how fiber optic gyroscopes (FOGs) work using the Sagnac effect, their key features, and applications in aerospace, autonomous vehicles, and more. Learn why FOGs are revolutionizing navigation technology. Fiber optic gyroscopes (FOGs) have become a vital component in a wide range of industries, from aerospace to automotive and even in consumer electronics. These devices are used to measure angular velocity, providing critical data for navigation and control systems. But how do they work? In this blog post, we'll dive into the inner workings of fiber optic gyroscopes and explore their significance. What is a Fiber Optic Gyroscope? A fiber optic gyroscope is a type of gyroscope that uses the interference of light traveling through optical fibers to detect rotational movements. Unlike traditional mechanical gyroscopes, which rely on rotating mass, fiber optic gyroscopes use light as the medium to measure rotational changes, offering higher precision and reliability. These gyroscopes are compact, durable, and ideal for high-precision applications. The Working Principle of a Fiber Optic Gyroscope At the heart of a fiber optic gyroscope is a concept called the Sagnac effect, which is key to understanding how these devices work. Here’s a step-by-step breakdown: 1. Light Splitting: A laser beam is split into two separate beams that travel in opposite directions around a coil of optical fiber. The optical fiber is typically wound into a coil to increase the distance the light travels, thereby enhancing sensitivity. 2. Rotation and Phase Shift: When the gyroscope is rotated, one of the beams of light travels slightly faster in the direction of rotation, while the other beam travels slower in the opposite direction. This causes a phase shift between the two light beams. The faster-moving beam is delayed, and the slower-moving beam is accelerated. 3. Interference: After the light beams travel around the coil and return to the detector, the phase shift results in interference between the two beams. The degree of this interference is proportional to the rate of rotation of the gyroscope. 4. Measurement: The interference pattern is detected by a photodetector, which converts it into an electrical signal. This signal is then processed to determine the angular velocity or rate of rotation of the gyroscope. The greater the phase shift, the faster the rotation. Key Features of Fiber Optic Gyroscopes 1. Precision and Sensitivity: Fiber optic gyroscopes are highly sensitive, capable of measuring very small changes in angular velocity with great precision. This makes them ideal for applications requiring fine navigation and control. 2. No Moving Parts: Unlike mechanical gyroscopes, which rely on moving components, fiber optic gyroscopes have no moving parts. This enhances their reliability and reduces the potential for wear and tear over time. 3. High Durability: The lack of mechanical parts makes fiber optic gyroscopes highly durable and resistant to shock and vibration, making them ideal for use in demanding environments like aerospace and military applications. 4. Compact Design: Fiber optic gyroscopes are generally smaller and lighter than traditional gyroscopes, making them suitable for use in applications where size and weight are critical factors. Applications of Fiber Optic Gyroscopes The versatility and accuracy of fiber optic gyroscopes make them essential in many fields: 1. Aerospace: FOGs are extensively used in aircraft and spacecraft for navigation and control systems. They help in maintaining stability, direction, and altitude, especially in GPS-denied environments. 2. Autonomous Vehicles: Fiber optic gyroscopes play a crucial role in the navigation systems of self-driving cars and robots, helping them to maintain precise positioning and orientation. 3. Marine Navigation: In submarines and ships, FOGs are used to provide precise heading and positioning data in situations where traditional navigation systems may not work effectively. 4. Military: FOGs are vital for tactical navigation systems, where high accuracy and reliability are essential for the success of military operations. 5. Consumer Electronics: FOGs are also finding their way into consumer products like gaming devices, camera stabilization systems, and even virtual reality equipment. Typical Product Parameters and Applications Take the G series fiber optic gyroscope as an example: G-F50 accuracy: 0.1 - 0.3°/h G-F60 accuracy: 0.05 - 0.2°/h The application fields include: small IMUs, INS, missile guidance head servo tracking, photoelectric pods, unmanned aircraft, etc. These products demonstrate the extensive application prospects of fiber optic gyroscopes in both military and civilian field Conclusion Fiber optic gyroscopes represent a significant advancement in rotational measurement technology. By using light instead of mechanical components, they offer superior precision, reliability, and durability. As industries continue to require more accurate and compact navigation solutions, the role of fiber optic gyroscopes will only continue to grow, enabling advancements in everything from autonomous vehicles to aerospace engineering.   Next time you hear about a self-driving car, an aircraft, or any high-tech navigation system, there’s a good chance that a fiber optic gyroscope is helping ensure smooth, precise movement.

Explore how low-pressure environments in space affect quartz flexible accelerometers, their performance in aerospace applications, and why they remain ideal for micro-vibration monitoring.   In the monitoring of micro-vibration in the orbit of spacecraft, the quartz flexible accelerometer, with its high sensitivity and low noise characteristics, has become an ideal sensor choice for measuring static and dynamic accelerations. However, will the low-pressure environment in space affect its performance? This article will deeply explore this key issue.   Why is a low-pressure environment so crucial for accelerometers?   Imagine that when the spacecraft is operating in the low Earth orbit at a height of 500 kilometers from the ground, it is in a high vacuum environment with a vacuum degree of approximately 10⁻⁵ to 10⁻⁶ Pa. And when the quartz flexible accelerometer product is packaged, the internal pressure is 1 atmosphere. What effects will this pressure difference bring?   As the in-orbit operation time increases, the air inside the package will gradually leak out, and the air pressure will continuously decrease, eventually reaching equilibrium with the vacuum environment of space. During this process, the average free path of air molecules will continue to increase and even exceed 30 µm. The flow state will also gradually transition from viscous flow to viscous-molecular flow, and finally enter the molecular flow state when the pressure is lower than 102 Pa.   How does the change in air pressure affect the performance of the sensor?   In an air environment, the movement of the sensitive diaphragm of a quartz accelerometer is affected by the membrane damping effect. However, as the air pressure decreases, the air damping becomes smaller and smaller. In the molecular flow state, it almost reaches zero, leaving only electromagnetic damping.   The key issue lies in this: If there is a significant gas leakage during the mission's duration, the membrane damping coefficient will drop significantly, which will alter the characteristics of the accelerometer and prevent the scattered free vibration from effectively decaying. Eventually, this may affect the scale factor and noise level of the sensor, thereby threatening the measurement accuracy.   How significant is the influence of low pressure on the scale factor?   The analysis of static calibration using the gravity inclination method shows:   In an air environment, the forward force acting on the pendulum component is mg₀, and the buoyant force f_b is ρVg₀. The electromagnetic force f is equal to the difference between the gravitational force and the buoyant force: \[ f = mg_0 - ρVg_0 \]   Among them: The mass of the pendulum m = 8.12×10⁻⁴ kg The density of dry air ρ = 1.293 kg/m³ The volume of the moving part of the pendulum component V = 280 mm³ The gravitational acceleration g₀ = 9.80665 m/s²   The calculation shows that the proportion of buoyancy to the weight of the pendulum component itself is approximately 0.044%. This means that in a vacuum environment, when the air pressure reaches equilibrium inside and outside, the scale factor of the quartz flexible accelerometer changes by only 0.044%.   Performance in practical applications Theoretical analysis indicates that the influence of low-pressure environments on the sensor scale factor is less than 0.1%, and the impact on measurement accuracy is negligible. It is particularly worth mentioning the AC-1 series of quartz flexible accelerometers, which is a model specifically designed for aerospace applications. Among them, the AC-1A model has the highest accuracy and possesses the following excellent characteristics: - Zero bias repeatability ≤ 10 μg - Scale factor 1.05 - 1.3 mA/g - Scale factor repeatability ≤ 15 μg   These performance indicators make them perfectly suitable for monitoring the micro-vibration environment of spacecraft in orbit, and they can also be applied to inertial navigation systems with high precision requirements and static angle measurement systems.   Conclusion: The feasibility of space applications   The comprehensive analysis indicates: 1. The maximum impact of the vacuum environment on the scale factor is no more than 0.044%. 2. The influence of the low-pressure environment on the sensor scale factor is less than 0.1%. 3. The impact on measurement accuracy can be disregarded.   Therefore, the quartz flexible accelerometer is perfectly suitable for long-term in-orbit applications. The low pressure or vacuum environment has very little impact on its scale factor and noise. This conclusion provides a reliable technical guarantee for the monitoring of spacecraft micro-vibrations, and also demonstrates the outstanding performance of the quartz flexible accelerometer in extreme environments.   AC-1 Whatever you needs, Micro-Magic is at your side.

Whether it is marine surveying, land measurement, or navigation for unmanned aerial vehicles (UAVs), robots, or helicopters, MEMS GNSS/INS can provide outstanding performance. Today, let's talk about its five core advantages.   一、What is MEMS GNSS/INS? MEMS GNSS/INS is a technology that integrates MEMS inertial navigation system (MINS) with global navigation satellite system (GNSS). By combining the advantages of both, it can provide high-precision position (Position), velocity (Velocity) and attitude (Attitude) information, which is abbreviated as PVA. GNSS: Provides absolute position information through satellite signals, but is susceptible to interference or interruption of the signals. INS: Based on inertial sensors, it can continuously output motion data, but there is a problem of error accumulation.   The complementarity of the two enables the integrated system to not only suppress the drift of inertial navigation but also make up for the instability of GNSS signals, thereby achieving high-precision navigation over both short-term and long-term periods.   二、Analysis of Five Major Advantages 1.

Through the optimization of power supply cycles and low-power modes, the energy consumption of MEMS GNSS/INS is much lower than that of traditional inertial navigation systems. For devices powered by batteries (such as drones), this means longer mission times and fewer charging requirements, significantly enhancing operational efficiency.   5. GNSS integration enhances accuracy Simple MEMS INS can only calculate the motion trajectory based on relative positions, while GNSS can provide absolute positioning. The combination of the two not only compensates for each other's shortcomings but also corrects the accumulated errors of MEMS INS through filtering algorithms, achieving higher-precision navigation.   三、Outstanding Solution: Micro-Magic MEMS INS As a leader in inertial navigation technology, Micro-Magic has launched three GNSS-assisted MEMS INS products with different levels of accuracy, covering requirements for surveying, tactical, and industrial applications.

Explore the impact of temperature drift on Fiber Optic Gyroscopes (FOGs), effective compensation methods, and experimental results. Learn how third-order polynomial models improve accuracy by 75%. Fiber Optic Gyroscopes (FOGs), as a new type of high-precision angular rate measurement instrument, have been widely used in military, commercial, and civilian applications due to their compact size, high reliability, and long lifespan, demonstrating broad development prospects. However, when operating temperatures fluctuate, their output signals exhibit drift, significantly affecting measurement accuracy and limiting their application scope. Therefore, studying the drift patterns of FOGs and implementing error compensation has become a critical challenge to enhance their adaptability in varying temperature environments. Mechanisms of Temperature Effects on Fiber Optic Gyroscopes FOGs are optical gyroscopes based on the Sagnac effect, composed of a light source, photodetector, beam splitter, and fiber coil. Temperature impacts gyroscope accuracy by interfering with the performance of internal components: Fiber Coil: As the core component, the fiber coil generates the Sagnac effect when rotating relative to inertial space. Temperature disturbances disrupt the structural reciprocity of the FOG, leading to phase difference errors. Photodetector: Environmental temperature variations introduce significant noise in the detector and produce a temperature-dependent dark current. The load resistance of the detector is also affected by temperature. Light Source: The temperature performance of the light source is closely related to the precision of the Sagnac phase shift. Variations in output power, mean wavelength, and spectral width under different temperatures further influence the gyroscope's output signal. Existing Methods for Temperature Drift Compensation Currently, there are three primary methods to mitigate temperature drift: Hardware Temperature Control Devices: Adding localized temperature control systems to FOGs can compensate for temperature errors in real time. However, this increases volume and weight, conflicting with the trend toward miniaturization. Mechanical Structure Modifications: Techniques like the quadrupole winding method ensure symmetric temperature effects on the fiber coil, reducing non-reciprocal interference. However, residual drift still affects angular rate detection. Software Modeling Compensation: Establishing temperature models for compensation saves space and reduces costs, making it the mainstream method in engineering practice. Temperature Experiments and Modeling Analysis Experimental Design Tests were conducted in three temperature ranges: 0°C to 20°C-40°C to -20°C40°C to 60°C The initial temperature of the thermal chamber was set, maintained for 4 hours, and then adjusted at a rate of 5°C/h. Gyroscope output data was recorded. The test system is shown in Figure 1, with a sampling interval of 1 second and data smoothed over 100 seconds. Key Findings Analysis of the output curves revealed: The gyroscope output exhibited significant oscillations with temperature changes. The output curve followed the same upward or downward trends as the temperature rate curve. Temperature drift was closely related to internal temperature and its rate of change.  Compensation Model A third-order polynomial compensation model was developed, incorporating the following factors: Temperature Factor Model: Lout=L0+∑i=13ai(T−T0)i+∑j=13bjTjLout​=L0​+i=1∑3​ai​(T−T0​)i+j=1∑3​bj​Tj​ After compensation, the bias stability reached 0.0200°/h. Temperature Rate Model:Introducing the temperature rate term improved bias stability to 0.0163°/h. Comprehensive Model:By considering both temperature and its rate of change, bias stability significantly improved to 0.0055°/h, achieving a 77% reduction in error. Segmented Compensation Results Different parameters were applied for compensation across temperature ranges, with results as follows: Gyro Axis Temperature Range Pre-Compensation Error (°/h) Post-Compensation Error (°/h) Error Reduction Percentage X-Axis 0°C to 20°C 0.02504 0.00518 79%   -40°C to -20°C 0.02404 0.00550 77%   40°C to 60°C 0.02329 0.00603 74% Y-Axis 0°C to 20°C 0.02307 0.00591 74%   -40°C to -20°C 0.02535 0.00602 76%   40°C to 60°C 0.02947 0.00562 80% Z-Axis 0°C to 20°C 0.01877 0.00495 74%   -40°C to -20°C 0.02025 0.00649 73%   40°C to 60°C 0.01413 0.00600 58% After compensation, the oscillation amplitude of the output curves was significantly suppressed, becoming more stable. The average error reduction across the three temperature ranges was approximately 75%. Conclusion and Outlook The proposed third-order bias temperature compensation model, which accounts for current temperature, initial temperature deviation, and temperature rate, has been experimentally proven to effectively improve gyroscope output signals and significantly enhance accuracy. This method can be applied to Micro-Magic's FOG models such as U-F3X80, U-F3X90, U-F3X100, U-F100A, and U-F300. However, current research still has limitations, such as discontinuous temperature history and insufficient sample coverage. Future work should focus on developing compensation methods for temperature drift across the full temperature range. For engineering applications, software modeling compensation demonstrates great potential as a cost-effective solution to balance precision and practicality.   U-F3X90 Whatever you needs, Micro-Magic is at your side.

Today, we will delve into the working principles, current market status, and typical product applications of this technology, with a special focus on the performance characteristics of tactical-grade fiber optic gyroscopes. 2. Working Principles of Fiber Optic Gyroscopes A fiber optic gyroscope is an all-solid-state fiber optic sensor based on the Sagnac effect. Its core component is a fiber optic coil, where light emitted by a laser diode propagates in two directions along the coil. When the system rotates, the propagation paths of the two light beams produce a difference. By measuring this optical path difference, the angular displacement of the sensitive component can be precisely determined. Simply put, imagine emitting two beams of light in opposite directions on a circular track. When the track is stationary, the two beams will return to the starting point simultaneously. However, if the track rotates, the light moving against the rotation direction will "travel a longer distance" than the other beam. The fiber optic gyroscope calculates the rotation angle by measuring this minute difference. 3. Technical Classification and Market Status Based on their working methods, fiber optic gyroscopes can be divided into: Interferometric Fiber Optic Gyroscope (I-FOG) Resonant Fiber Optic Gyroscope (R-FOG) Brillouin Scattering Fiber Optic Gyroscope (B-FOG) In terms of accuracy levels, they include: Low-end tactical gradeHigh-end tactical gradeNavigation gradePrecision grade Currently, the fiber optic gyroscope market exhibits dual-use characteristics for military and civilian applications: Military applications: Attitude control for fighter jets/missiles, tank navigation, submarine heading measurement, etc. Civilian applications: Car/aircraft navigation, bridge measurement, oil drilling, etc. It is worth noting that medium-to-high precision fiber optic gyroscopes are primarily used in high-end military equipment such as aerospace, while low-cost, low-precision products are widely applied in civilian fields like oil exploration, agricultural aircraft attitude control, and robotics. 4. Technical Challenges and Development Trends The key to achieving high-precision fiber optic gyroscopes lies in: 1. Studying the impact of optical devices and physical environments on performance. 2. Suppressing relative intensity noise.
