摘要
以大型测地型激光陀螺仪为研究对象,对近几年的相关研究进展进行了总结.首先阐述大型激光陀螺仪原理及其在测地学、旋转地震学、基础物理等领域的相关应用;然后根据运转机制的不同,介绍主动和被动激光陀螺仪的工作原理,并分析国内外大型主、被动激光陀螺仪的研究现状;最后从高Q值环形腔、超稳参考光源、陀螺仪闭环锁定、环形腔腔长稳定控制等方面详细介绍面向精密重力测量国家重大科技基础设施(PGMF)建设的大型被动激光陀螺仪的研究进展,同时指出该系统目前的受限因素及未来大型激光陀螺仪的研究方向.
The large-scale geodetic laser gyroscope is the research object,and specifically the relevant research progress in recent years were summarized.Firstly,the principles of the laser gyroscope and its related applications in the fields of geodesy,rotational seismology,and fundamental physics were explained.Then,laser gyroscopes were divided into the two types according to the different operation modes,and the current research status of the active and the passive laser gyroscopes in the world were introduced.Finally,the large-scale passive laser gyroscopes based on the national precise gravity measurement facility(PGMF)in Huazhong University of Science and Technology were detailed,including the high Q-factor ring cavity,ultra-stable laser light source,the closedloop locking operation,cavity length stabilization,etc.At the same time,the current limitations of the system and future research directions were also presented.
