Virtual Prototyping of Measurement Setup for Complex Light Scattering Properties
The objects with complex light scattering, for example, light guiding plates with surface and volume microstructures are widely used in modern optical devices and computer graphics. Typically, such properties are described with Bi-Directional Scattering Distribution Function (BSDF) which totally describes the dependence of scattering properties on illumination and observation conditions. The precise BSDF measurements require complex setups with high resolution and launching numerous measurements in the entire angular space. The virtual prototyping of BSDF measurement devices is a difficult and problematic task because of the very small efficiency of similar systems. In the given paper the optimal and more effective ways to simulate such devices are presented based on example of patented scheme for portable BSDF measurements setup, including tolerance calculation and accuracy estimation.
