摘要
介绍了哈特曼法检测眼镜片的测量原理及对远轴光线的屈光度补偿,采用哈特曼法对渐进多焦点镜片进行检测。提出了实验总体方案并得到CCD采样图,通过后续图像处理,理论上可以得到镜片的屈光度分布图。结果表明,哈特曼法检测渐进多焦点镜片结构简单,方便可行。
Hartmann test for progressive addition lenses is proposed in this paper. The measurement principle of Hartmann test for ophthalmic lenses and the power compensation of peripheral rays are introduced. The experimental setup used to test lenses is put forward and the sample images from CCD are obtained. The power distribution map for lenses can be obtained by image processing in theory. The results indicate that Hartmann test for progressive addition lenses is convenient and feasible, and its structure is simple.
