Abstract

In recent years, in order to meet the urgent requirements of improving the volume-efficiency ratio of optical fiber inertial navigation components in various application fields such as sea, land, air and space, the integrated optical fiber gyroscope technology using optical chip integration and micro high-precision fiber coil has developed rapidly. As the sensitive core of integrated fiber optic gyroscope, the precision and reliability of micro high-precision fiber optic loop determine the precision and Technology maturity of integrated fiber optic gyroscope. This paper first introduces the basic composition of fiber optic gyroscope using optical chip integration scheme, then focuses on the micro high-precision fiber coil technology using multipole orthogonal winding and vacuum glue filling process, and creatively puts forward the reliability detection scheme of multi parameter fiber coil process. Through the multi parameter nondestructive testing technology, the manufacturing process defects of micro and small optical fiber coil are found, the manufacturing process is optimized, and an effective method to improve the process reliability of micro and small optical fiber coil is put forward. Finally, through the reliability accelerated test, the reliability improvement method of micro optical fiber coil process mentioned in this paper is verified. This paper has practical significance for the development and engineering application of integrated fiber optic gyroscope technology.
