An optic fiber gyroscope testing method and device, a storage medium and computer equipment

Abstract

The invention relates to an optic fiber gyroscope testing method and device, a storage medium and computer equipment. The method includes acquiring corresponding parameters of a light source in a light path of an optic fiber gyroscope, optical fiber butt fusion points, a polarization maintaining optical fibre segment and a polarizer; acquiring a polarization crosstalk measurement result of a polarization maintaining optical fibre loop in the optic fiber gyroscope; and according to the corresponding parameters of the light source in the light path, the optical fiber butt fusion points, the polarization maintaining optical fibre segment and the polarizer, and according to the polarization crosstalk measurement result of the polarization maintaining optical fibre loop, operating an optical path transmission physical model set in advance to acquire quality parameters of the optic fiber gyroscope. Through the method, quality of the optic fiber gyroscope can be evaluated before the optic fiber gyroscope is subjected to a high- and low-temperature actual measurement, and the gyroscope quality before actual measurement is assessed in advance and can be adopted as a reference for actual measurement to prevent a phenomenon that a large error in an actual measurement process is unaware, thus increasing testing precision and ensuring accuracy of a testing result.

Description

technical field [0001] The invention relates to the technical field of fiber optic gyroscopes, in particular to a testing method, device, storage medium and computer equipment for fiber optic gyroscopes. Background technique [0002] The interferometric fiber optic gyroscope is an angular velocity sensor used for inertial navigation. It has broad development and application prospects in many military and civilian fields such as inertial guidance, vehicle positioning, and underground detection. In the actual production and application process, due to the fluctuation of the degree of polarization of the light source, the defects of the welding points between the pigtails of the components in the optical path, the unsatisfactory extinction ratio of the Y waveguide, and the large number of polarization crosstalk points in the polarization maintaining fiber ring, and with the external As the ambient temperature changes, the intensity and position of these polarization crosstalk p...
