谐振式光学陀螺的激光频率锁定技术设计
Design of laser frequency lock for resonant optical gyro
摘要
Abstract
In this paper, the construction and principle of resonant optical gyro system are analyzed and de-signed, and the current research status of the gyro is introduced. At the same time, this paper presents a super-position digital locking algorithm for the laser frequency locking of resonant optical gyro, with the proportion integral (PI) controller, compares to the frequency lock loop can improve the frequency locking feedback re-sponse, reduces the system power consumption. Through the rotation test of gyro system, and the Allan vari-ance fitting calculation of an hour of zero-bias stability, proves that the article designed digital lock frequency algorithm can meet the demand of resonant optical gyro system testing, and the accuracy of laser frequency locking has reached the expected goal.关键词
