Lighting design or stray light simulation of imaging or non-imaging optical systems requires a precise specification of the optical properties of the scattering materials and one of the ways of the proper specification is the Bidirectional Scattering Distribution Function (BSDF). Although, it is possible to obtain data about the optical properties of the sample for example by measurement of the BSDF, but it is difficult to extract the properties of the sample components (BSDF of the sample boundary, parameters of volume scattering, etc.). In such cases, it is required to reconstruct these properties. For this operation, there are many methods, like the reconstruction of the BSDF of the microrelief, but they not applicable in cases when the volume scattering is used. Authors have developed a method for optimization of the volume scattering media parameters, which shows good agreement with the measurements of the sample BSDF.
