SIMULATOR FOR SIMULATING THE OPERATION OF A FIBER OPTIC GYROSCOPE

摘要

A method includes simulating operation of a fiber optic gyroscope during a digital simulation. The simulation includes performing an iterative loop that includes simulating an intensity of light from a fiber coil of the fiber optic gyroscope and simulating operation of one or more control loops within the fiber optic gyroscope using the simulated intensity of the light. The intensity of the light is simulated using a sine/cosine function based on at least one angular rate-related effect injected into the simulation as a Sagnac phase shift. The simulated operation of a first of the one or more control loops attempts to reduce or eliminate the Sagnac phase shift. The method also includes storing, outputting, and/or using results of the simulation. The at least one angular rate-related effect could include rotation of the fiber coil and/or mechanical vibration of the fiber coil.
