基于莫尔条纹偏折原理，本文提出多点检测多焦点镜片的方法。为了提高镜片屈光度的检测精度，本系统在光路中引入了空间滤波器，在算法上采用了八邻域处理方法，测量精度达到了5%。为了验证本设计方案，设计了实验系统进行验证，利用CCD摄像机对图像进行采集，并用MATLAB对图像进行处理，检测多焦点镜片屈光度，最后对多焦点镜片进行了实际测量。通过实验验证，结果表明本系统及检测方法有很好的效果。

A new method about progressive addition lenses ’ power detection based on the moiré deflection tech-nology is proposed. In order to improve the detection accuracy, a spatial filter was added into the optical path and an algorithm named eight-neighborhood was used in the system. In the designed experimental program, we used a CCD camera to capture the image, and the MATLAB to process images. Finally, a progressive addition lens was de-tected and the results show that the present system and the detection method have a good effect.
