  • Bidirectional reflectance distribution function(BRDF) can be used to study the laser scattering properties of target surface.A setup for the measurement of scattering characteristics of the sample's BRDF was designed in the laboratory.The powder pressboard of BaSO4 was used as the standard reflection board.The spatial distribution of reflected light intensity was obtained at different roughness and incident angles. The sample's BRDF at space was obtained. The results indicate that the lower the roughness of the surface plate, the larger the BRDF in the mirror direction; the larger the incident angle, the larger the BRDF in the mirror direction;tacertain degree of diffusive reflection characteristics appears; and vice versa. Different surface roughness determines corresponding different degrees of laser scattering.
