Abstract

One of the key factors of laser gyro measurement error is the working state of the frequency stabilized servo system. Improving the performance of the frequency stabilized servo system is conducive to improving the measurement accuracy of the gyro. In this paper, a digital frequency stabilizing and locking servo system scheme of laser gyro is proposed. The locking control is added to the digital small jitter frequency stabilizing method to improve the measurement accuracy of the gyro and reduce the influence of laser gyro backlight scattering. With the addition of the lock control system, the gyro control 100-second variance increased from 8.92‰ ~ 11.7‰ to 6.11‰ ~ 6.96‰, and the precision improvement ratio was better than 22.3%.
