Experimental Study of Target Depolarization Characteristics Based on BRDF

摘要

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 thetypical surfaces (e.g., aluminium, epoxy, and F4 board), a multi-angular measurement device is established to quantifythese two parameters. With an incident laser beanm of 650 nm, a series of incident and detector view angles is measuredand the results show the significant variance in the parameters for different targets. A coincidence is proved between theevolution of the two parameters, which is also valuable in modeling pBRDF (polarized BRDF).
