Paper Abstract

A full-color auto-stereoscopic video display system has been introduced and developed using only a single phase-only spatial light modulator, a simple projection lens module, and three laser diode sources with the wavelengths of 635nm (red), 532nm (green), and 473nm (blue). Full-color stereoscopic input video frames are separated by each red, green, and blue component with respect to each stereo eye view for a 3D image frame. Each hologram is then optimized by a modified iterative Fresnel transform algorithm method, for the reconstruction of each gray-level quantized stereo image without color dispersion. To solve the color dispersion problem we applied scaling constraints and phase-leveling techniques for each hologram. Then the optimized holograms are synthesized with direction-multiplexed holograms and modulated by a single phase-type spatial light modulator. The modulated signals are Fourier-transformed by an achromatic lens and redirected to each viewer's eye for the reconstruction of the composed full-color auto-stereoscopic 3D display. Experimentally, we demonstrated that the designed computer-generated holograms were able to generate full-color stereoscopic 3D video images without any use of glasses.
