Abstract

A means of target surface reflectivity measurement is proposed in this paper. This means simulates the detection process of laser radar system whose emission direction and detection direction are parallel. By using a 532nm pulse laser as the source, several construction materials´ reflectivity are measured in a serial of experiments. The reflect intensity at different deflection angle of the materials are acquired. Through data analysis, the curves represent reflection intensity vary according to deflection angle is depicted. Base on these curves, samples in experiment could be divided into metal and nonmetal. At the end, a method, combining deflection angle with reflection intensity, is proposed to classify unknown material surface.
