目前环形激光器已发展成为角度和角速度传感器。在惯性导航和角度定位方面有重要的用途。本文介绍了环形激光器精密测量角度的试验,内容包括试验原理、四频环形激光器原理、测量结果及进一步提高测量精度的方法。本装置测量误差为±1秒左右(3σ)。不久用环形激光器将可能以优于±0.5秒的精度测量0～360度范围内的任一角度。
Ring lasers are currently being developed as angle and angular velocity sensors. An important use in inertial navigation and angle positioning. This paper introduces the experiment of precise measurement of ring laser, including the principle of experiment, the principle of quadruple ring laser, the measurement results and the methods to further improve the measurement accuracy. The measurement error of the device is about ± 1 second (3σ). Soon with a ring laser it is possible to measure any angle in the range of 0 to 360 degrees with better than ± 0.5 second accuracy.
