| Abstract: | A method for the measurement of scattering characteristics of the sample is proposed. The powder pressboard of F4(polytetrafluoroethylene(PTFE))was used as reflection standard board. We measured the reflection luminous intensity scattering data of sample and standard board. By transmiting through reflection standard board,we obtained the sample's BRDF at hemisphere space(λ= 1.06μm). Then we compared this result with the output result. of the model. The experimental result indicates that this method is a feasible to analyse the scattering characteristics of the sample. |
