Experimental study of target depolarization characteristics based on BRDF

The diffusion reflection and depolarization of material surfaces is closely relevant to the physical properties of materials. To investigate the connection between BRDF (binomial reflection distribution function) and depolarized capability of the typical surfaces (e.g., aluminium, epoxy, and F4 board), a multi-angular measurement device is established to quantify these two parameters. With an incident laser beanm of 650 nm, a series of incident and detector view angles is measured and the results show the significant variance in the parameters for different targets. A coincidence is proved between the evolution of the two parameters, which is also valuable in modeling pBRDF (polarized BRDF).
