激光陀螺锁区特性的研究
The Study of Laser Gyro Lock-in Characteristic
摘要
从理论和试验两个方面,研究了四边形腔环行激光陀螺的锁区特性.利用环行腔中背向散射光束具有相干性,导出了环行谐振腔综合背向散射与反射镜、反射镜之间的相对位置的关系.在有两个位移反射镜的四边形谐振腔中,理论上得到了综合背向散射系数与谐振腔腔长具有双波长周期.利用综合背向光强实验及锁区与陀螺工作模数实验分别验证了理论的正确性.试验证实散射光的强度与谐振腔的工作模数存在双模周期性,综合背向散射系数大,陀螺锁区大,反之亦然.
Abstract
Lock-in characteristic of four-mirror ring laser gyro was studied both by theory and experiments. The relationship between cavity overall back-scatter with the back-scatter of the mirrors and distance between mirrors was given. The cavity overall back-scatter was of two wave length period in cavity length. The results of two experiments are validated this relationship.
