Paper Abstract

This study combines the methods of the Stokes parameters and genetic algorithm (GA) with the mathematical model in the depolarized fiber optic gyroscope (FOG) for finding the optimal structure of FOG. An effective model to simulate a SM fiber coil and genetic algorithm for finding minimum bias errors are proposed for solving the problems of polarization errors and signal-fading in the depolarized FOG. As a result of analysis in model, the minimum bias error can be found as 4.4×10-5 °/hour with 1000 m in length of the fiber coil. As the authors' knowledge, this is the first idea in simulating the effective parameters of a SM fiber coil and using GA in finding the optimal structure for the depolarized fiber optic gyroscope.
