Low Price Micro-Nano Fiber Optic Gyroscope for Inertial Measurement Unit

Fiber optic gyroscope uses optical methods to achieve angle measurement, so it can be started instantly without preheating time. This makes fiber optic gyroscopes perform well in application scenarios that require fast response. Fiber optic gyroscope has a wide dynamic range and can adapt to measurement requirements at different speeds and accelerations. The internal structure of fiber optic gyroscope is relatively stable and not easily affected by external vibrations. This enables fiber optic gyroscopes to function properly in rugged environments or when subjected to impacts. Some high-end fiber optic gyroscopes also adopt special anti vibration designs, further improving their anti vibration capabilities.

The performance characteristics of fiber optic gyroscopes are mainly reflected in high precision, high stability, fast response, anti vibration, and compact structure. Fiber optic gyroscope can achieve high-precision angular velocity measurement through precise optical technology and signal processing algorithms. Its accuracy can reach 0.01 °/h or even higher, which is crucial for applications that require high-precision navigation and positioning. In the design and manufacturing process of fiber optic gyroscopes, measures such as optimizing fiber optic wrapping technology and using high birefringence fibers have effectively reduced error factors such as noise and drift, and improved measurement accuracy.

The development of fiber optic gyroscopes faces some technical difficulties, such as sensitivity loss, drift caused by noise and fiber birefringence, and unstable scaling factor caused by polarization state changes. In order to overcome these difficulties, researchers are constantly exploring new technologies and methods, such as using high birefringence fibers and optimizing fiber optic wrapping techniques. In the civilian field, fiber optic gyroscopes are mainly used for automatic navigation, positioning and orientation, vehicle control of ground vehicles, as well as attitude control of agricultural aircraft, positioning tools and rescue tools in underground engineering maintenance.
