摘要
环形激光是指在环形腔体内传播的激光。环形激光基于Sagnac效应而具有特殊的应用价值。介绍了环形激光的工作原理、发展状况、应用情况。重点介绍了环形激光在惯性导航领域的应用和角度计量领域的应用,包括激光陀螺的介绍及环形激光动态测角仪在动态测角方面的应用,指出了环形激光应用的研究方向。
The laser with a ring cavity（ring laser） is suggested.The principle of RL measurement is the effects of Sagnac,For this serval advantages are given to RL.Working principal,the sustainable development,possible applications are intruduced.It is used as a sensor such as ring laser gyro（RLG） in inertial navigation system.It is also used to make a dynamic goniometer for different applications of precision angle measurement.A study direction of the Application is found.
