Theoretical and experimental investigation to signal detection system for laser gyroscope

In this paper,we present a novel,low noise and large dynamic range signal detection system for a four frequency differential laser gyroscope.Introducing the mathematical mechanization,we employ decomposition method,which is a theoretical method to solve nonlinear dynamical system,to analyze the model of our system and give the experimental results to verify the theoretical analyzation.According to the decomposition method,the analytical solutions of phase difference,frequency difference and variation rate of frequency difference,which correctly express the parameters of system response time and stable state procedure of the closed phase loop,can be obtained.Based on the theoretical analysis,the signal detection system has been developed.The experimental results show that the system has the ability of large dynamic range and rejecting of noise and meet the requirement of laser gyroscope.
