Analysis and Simulation of Laser Polarization Characteristics on Metal Surface in Short-Range Detection

In view of using only the intensity information of retroreflection wave and poor capacity of anti-interference in laser short-range detection, this paper analyzes the polarization characteristics of laser beam on the metal surface and establishes reflection model of polarized laser. A target detection method based on polarization characteristics of reflection laser is putted forward and the simulation of polarization characteristics on the surface of several typical metal targets is implemented at last.
