Abstract
The importance of the diffuse reflectivity of the reflective target for the non-cooperative laser rangefinder is presented. In order to measure the diffuse reflectivity, the experiment is designed, and the principle and method of the experiment are described in detail. According to the experimental results of several materials, the relation between the different diffuse materials, different incidence angle and the diffuse reflectivity are analyzed. The off specular peak reflection is introduced specially. The experiment verified that the diffuse reflectivity varied with the incidence wavelength. The diffuse reflectivity of the reflective target must be considered when we choose the light source of laser rangefinder.
