3D visualization system consists of a multilayer optical shutter screen and a projection system. High-frame rate projector projects images on shutter screen. Projector is based on spatial light modulator (for example, Texas Instruments Digital Micromirror Device), that consists of a number of micromirrors, displaying a binary image. To achieve image with desired color depth, several light modulation methods can be used – binary pulse width modulation, light source intensity modulation and mixed modulation. Color depth is defined in a number of bits per pixel (or color), for example, for three colors, 8 bits per color there are 16.7 million color variances.
