The Study of Laser Gyro Output Noise Characteristic
激光陀螺噪音特性试验研究

The method for analysis of laser gyro output noise and the model of the noise are given.Using the model,the output noises of four types of laser gyro are analyzed by different de-modulating ways in theory and experiments.The noise term and its causes are researched theoretically.The experiment data and noise curve are given.The results show that the model can be used for evaluating the random walks coefficient,the quantization error,de-modulating errors,and the output rate noise of the laser gyro.
