Modeling and simulation of an optical system for surface roughness measurement

A novel model of an optical system for surface roughness measurement is proposed, which is based on the study of the scattering characteristic of rough surfaces and theories for intensity-modulated fiber optic sensors. The effect of the rough surfaces and the fiber optic sensor head to the measurement model are analyzed respectively. In order to guide the surface roughness measurement experiment, some simulation of the optical system has been done on a computer. Though the modeling and simulation of the surface roughness measurement system are under certain assumptions and conditions, the research results are valuable to experiment applications yet.
