本文提出一种利用激光干涉技术测定磨边透镜中心偏差的方法。根据等厚干涉的基本原理，用平行的激光束投射到磨边工件表面，可以得到两个干涉同心圆，这两个像分别反映了工件前后表面的球心点位置。适度调节这两个像即可达到透镜允许的中心偏差精度 This paper presents a method using laser interferometry to measure the center deviation of edging lenses. According to the principle of isometric interference, two interfering concentric circles can be obtained by collimating the parallel laser beam onto the surface of edging workpiece. These two images respectively reflect the position of the center of the ball before and after the workpiece. Moderate adjustment of these two images to achieve the center lens allows the accuracy of the error
