Gyroscope is the core of inertial navigation system, which is the key factor affecting the performance of inertial navigation system. Especially the fiber optic gyro, its rapid development has created a new situation of inertial navigation system, with pure solid state no moving parts, simple process, wide precision coverage, large dynamic range, fast start, long life and other advantages, fiber optic gyro in many fields have a wide range of applications. If you are looking for a low-cost fiber optic gyroscope with high performance, Ericco offers FOG: ER-FOG-910(https://www.ericcointernational.com/gyroscope/fiber-optic-gyroscope/er-910-fiber-optic-gyro.html), which can be used in drone flight control, inertial measurement unit, surveying and mapping, track inertial traverse road test, photoelectric pod and many other fields.
Based on Sagnac effect, fiber optic gyroscope is a new type of fiber optic angular rate sensor. With the development and maturity of fiber optic technology in recent years, FOG has gradually developed into the mainstream instrument in the field of inertia technology, but it also has technical limitations, among which high temperature and mechanical vibration are the main limiting factors that cannot be ignored.
Influence of mechanical vibration on fiber optic gyroscope and its reduction measures
Mechanical vibration is one of the unavoidable environmental factors in the application of fiber optic gyroscope. How to keep the high precision of FOG under the condition of mechanical vibration is the content that must be considered in the design and engineering application of FOG. It is assumed that the optical path is reciprocal, that is, in the optical fiber ring, the distance traveled by the light transmitted in the opposite direction is equal, but under normal circumstances, the change of environmental factors (such as mechanical vibration) brings non-reciprocity in the optical fiber ring, which will affect the performance of the FOG, resulting in angular velocity measurement errors.
Based on the theoretical analysis of the mechanism of mechanical vibration affecting the performance of optical fiber gyroscope, the concept of "matching point" is introduced into the optical fiber ring. It is pointed out that the closer the spatial position of "matching point" in the optical fiber ring, the better the vibration performance of the gyro is. The effect of mechanical vibration on the performance of fiber optic gyro is suppressed.
