Description

technical field

[0001] The invention relates to a non-destructive detection device for the optical path of an optical fiber gyroscope, in particular to a device for detecting defects in the optical path at the rear end of an optical fiber gyroscope, which belongs to the technical field of optical fiber gyroscope detection. Background technique

[0002] Fiber optic gyro is a new type of all-solid-state inertial instrument with high reliability and long life. After more than ten years of hard work, domestic fiber optic gyro technology has been successfully applied to many weapons and aerospace models. With the in-depth advancement of various types of tasks, the reliability and long life requirements of fiber optic gyroscopes are getting higher and higher.

[0003] The fiber optic gyroscope's light source, fiber coupler, Y waveguide, fiber ring and other optical devices are connected to each other through optical fibers, and optical fibers are the weak link in reliability. In ...
