采用Hindle球方法检测凸非球面是人们常用的经典方法之一
此方法的优点是检验精度高、操作简单.为了解决经典Hindle球检验离轴凸非球面所需的Hindle球口径过大的问题
提出采用离轴Hindle球检验离轴凸非球面的方法.此方法中
Hindle球使用在离轴状态
通过旋转离轴凸非球面达到检验整个待检面的目的.此方法可以大大减小Hindle球的尺寸
从而间接增大了待检离轴凸非球面的尺寸.本文同时对此方法的测量精度进行了理论分析.
Hindle testing of the convex aspherical surface is one of the classical methods
which has the advantages of high accuracy and easy operation. In order to avoid the large aperture of Hindle ball when an off-axis convex aspherical surface is under testing
the authors suggest that it be done with off-axis Hindle ball. Hindle ball is used in off-axis configuration
at the same time it can be rotated so that the whole area can be tested. The size of Hindle ball can be reduced
thus the area in the aspherical surface to be tested is increased. The accuracy of the method is also analyzed theoretically.
