Abstract

This paper addresses the issues of high qualification rates and consistency required in the engineering production process of Fiber Optic Gyroscope, and introduces the optical path scheme of Fiber Optic Gyroscope in conjunction with the characteristics of optical path transmission. Test method designs for the roles of involved optical devices in the gyroscope's optical path are presented, along with theoretical analysis calculations from aspects such as optoelectronic device tail fiber matching and loss matching. After applying optical device matching technology to the engineering of Fiber Optic Gyroscope, it effectively solved the consistency problem of the output signal assembly of the gyroscope's optical path, reduced the dispersion of the zero bias stability index at room temperature for engineering products, increased the proportion of products with an accuracy of 0.03°/h-0.05°/h from 52% to 87%, and raised the qualification rate for one-time testing at room temperature from 78% to 96%.
