초록

In this paper, we propose an BRDF measurement method based on laser light scattering, which is very effective for roughness measurement. The measurement setup has a very simple configuration, which consists of a collimated green laser, a detector. The experimental tests show that the BRDF measurement has difference between good Au Pad and bad Au Pad.
