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°.
