摘　　要：介绍用莫尔偏折术及电子外差读数技术测量楔角的方法,并给出楔角计算公式。该方法引入的测量误差约为1％,且它适于小角度测量。The method of measuring wedge angle by use of the Moire deflectometry and electronic heterodyne reading technique is introduced. The method is suitable for small angle with a measurement error of about 1%. The wedge angle calculating equations are given.
