摘　　要：光学测角法是高精度动态角度测量的一种有效的解决途径。对目前发展较快的几种角度测量的光学方法———圆光栅测角法、光学内反射小角度测量法、激光干涉测角法和环形激光测角法进行了详细的介绍 ,并且分别给出了每种方法的测量原理和发展现状 ,比较了各种方法的优缺点 。Optical methods are one of the most effective way of dynamic angle measurement with high accuracy. Several well developed optical methods of angle measurement, such as angle measurement with radical gratings, angle measurement based on internal reflection effect, laser interference angle measurement system and ring laser goniomcters, are described in detail. The principle, present status and application situation of each method is displayed. The superiority and defects of these methods are lined out. The development future of each method is given at last.
