摘要
光学方法是一种精确测量小角度的主要方法和重要手段.通过综述光学自准直法、内反射法、激光干涉法和环形激光法等测角方法的测量原理,给出典型实验装置,比较了各种方法的优缺点,并对它们的使用场合进行了探讨.
Optical methods is a main and important method for precise measuring small angle. The theory of the angle measurement based on optical autocollimation, internal reflection, interferometry and the ring laser geniomctor are described in detail. The typical measurement devices are listed. The superiority and defects of these methods are lined out, and the application situation of each method is discussed too.
