摘　　要：根据先前曾提出的单楔板旋转原理与实验研究,一种定量检测光学系统离焦量及激光发散度的仪器已经研制成功.本文概括地介绍了该仪器原理、主要功能、测试方法及精度评价等.由于本仪器具有一系列优点,已成为激光实验。A new shear plate collimation tester on the basis of a single wedge plate using two-time rotatable ways[1] have been developed[2]. It is mainly used to test laser beam collimation, divegrence and amount of defocusing of optical systems in collomator, beam expander and telescope. It can be also used to test wavefront aberrations and laser parameters and to adjust optical systems. In this paper. The basic principles, quantitative interpretation, accuracy analyses, functions and features of the tester are presented.
