摘要
通过控制参量提高陀螺精度和成品率,是激光陀螺工程技术研究的主要内容之一。引入相邻模陀螺零偏差及不平衡电流零偏差两个参量,对不同等级表陀螺对应参量的研究,发现陀螺性能与该参量具有确定的关系,通过控制这两个参量,可以有效提高陀螺使用精度和成品率。理论研究了两个参数变化的根源,分别为谐振腔参数及锁区的变化,为提高激光陀螺精度提供了一种有效的技术途径,对于进一步提高抖动陀螺精度具有实用价值。
In studying the laser gyro engineering technology, one of the main contents is to improve the accuracy of laser gyro and the rate of finished products by controlling the parameters. The bias difference of adjacent modes and the bias difference of unbalance discharge current were introduced into the performance evaluation system of laser gyro. According to the study on some different grades of laser gyro, the relationship between the two parameters and the performance of laser gyro were determined. By optimizing these two parameters, the accuracy of laser gyro and the rate of finished products can be effectively improved. Besides, the variation origins of the two parameters were studied, which are the variations of the resonant cavity and the lock-in, respectively. The two parameters provide an effective technical method to improve the precision of the laser gyro, and have practical value for further improving the precision of the mechanically dithered laser gyro.
