粗糙平面的激光散射特性研究
Research of laser scattering from random rough plane surfaces
摘要
Abstract
In order to test the edge of a target, the method of laser scanning, with which the target profile can be measured by detecting the change of return laser energy, was introduced. The random facet model was employed to establish the rough plane scattering theory, based on which the intensity distribution of the scattered laser from random rough plane surfaces can be calculated. By means of peak (valley) value detection or across-zero detection, the edge message of target can be obtained. The results prove that the proposed approach is effective on the detection of target profiles.关键词
