Method and verification for measuring surface roughness of components by angle resolved scattering method

This paper introduces the automatic measurement system of laser scattering method based on angular resolution. Discuss the principle of laser in optical element surface scattering, propose the method which use angle resolved scattering (ARS) method to measure surface roughness, at the same time the measurement principle experimental platform is built based on the experimental results after verifying the correctness of the angle resolved scattering method.
