几何像差的自动检测方法

THE AUTOMATIC MEASUREMENT METHOD OF THE GEOMETRIC ABERRATION

在传统的哈特曼（Ｈａｒｔｍａｎｎ）检测方法基础上，引入光电及图像处理的技术，实现对几何像差的自动检测、数据自动分析及输出．与照相法相比，降低了测量误差。

The principle of the optoelectronic measurement of Hartmanns method is studied by means of a CCD image sensor, the interface from a video to a computer and image processing by a computer. Compared with the measurement method by photography, the automatic measurement reduces the errors of results and raises operating efficiency greatly.
