| 摘 要： | 为了实现物体表面粗糙度的测量,基于激光散斑原理,利用灰度共生矩阵方法计算了激光散斑图像的基本参量,分析了激光散斑含有的物体表面粗糙度特征。在此基础上搭建了物体表面粗糙度激光散斑测量实验系统,采集了不同表面粗糙度标准样板在不同入射角条件下的激光散斑图,继而得到了研磨和平磨条件下散斑条纹对比度与光束入射角之间的关系。结果表明,入射角约为60°时,散斑特性及其对比度效果最好。

| Abstract: | In order to measure the surface roughness, based on laser speckle, the parameters of laser speckles were analyzed by means of gray level co-occurrence matrix least squares method. The measurement system of laser speckle was set up, and the images at different incident angles were compared. The results showed that the contrast of the laser speckles was best when the incident angle was 60°. |
