摘要：

In view of the existing BRDF tests are for planar targets, not for stereo targets, equivalent test method was proposed for stereo targets BRDF. By combining different reflectivity coating child-blocks into corresponding parent-block, stereo target spatial distribution of light scattering was equivalent. BRDF of axisymmetric cylinder target and its equivalent parent-block were tested by using the BRDF measuring system, and the curve correlation analysis was completed. The test results show that the BRDF equivalent method can measure the axisymmetric stereo targets and equivalent BRDF of stereo targets, when incident angle is small, or less than 30°. BRDF equivalent test method of axisymmetric stereo targets can be realized by founding planar ones. © 2020, Editorial Board of Journal of Infrared and Laser Engineering. All right reserved.
