非合作目标相位式激光测距中目标漫反射特性的实验研究

Diffuse Reflectivity of the Reflective Target for the Non-Cooperative Laser Rangefinder

阐述了目标的漫反射特性对非合作目标相位式激光测距仪中光功率探测的重要性。设计了一种测量漫反射性能的实验装置,并测量了几种材质的漫反射特性。针对实验结果分析了漫反射特性与不同材质和不同入射角的关系,并指出在其他条件相同时,目标的反射特性还与入射光的波长有关,因此,在选择测距仪的光源时还应考虑被测物表面的反射特性。

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.
