Problems solved by technology

However, after the optical fiber is wound and glued, the optical path at the back end has been closed by the fusion point, and it can no longer be connected to the detection equipment for detection. We can only try to detect the defect of the optical fiber through external observation, and the optical fiber is wound in the fiber ring cavity. This kind of optoelectronic device is relatively close to each other, and the optical fibers are wound into bundles and overlap each other, and the defects on the back of the optical fiber and the shielded area cannot be observed directly with an ordinary microscope

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 ...
