Abstract: The modern computer graphics tools allow to create realistic, physically adequate images. Necessary information about light scattering properties of real surfaces may be provided only by optical measurements. The direct usage of traditional optics devices is impossible because of great volume of needed measurements . A concept of new device was elaborated by authors, the device was designed and now it is in use. The device provides the measurements of spectral and spatial distribution of surface light scattering. The light guides are used for simultaneous measurements in numerous directions. The angle distribution near the direction of specular reflection is converted into spatial one via lens. This approach allows to reach a high spatial resolution in this critical area. The CCD-based video camera is used as a detector, for parallel processing of maximal volume of spatial information.
