Abstract

Attention is being paid to computer generated holograms (CGH) that can be formed by liquid crystal devices (LCD) because of their possible applications in electro-holography. In the research reported here the kinoform of an on-axis type CGH was constructed by using a commercially available TN type LCD as phase modulator, and the basic characteristics of its image were examined. Moreover an electro-holography system for color 3D animated image display was developed by using three LCD panels, RGB three lasers and graphics frame memory. A clear color image was reconstructed by taking into account the wavelength dependence of the size and position of the color image, then the characteristics of color gamut and animation of the reconstructed color image were evaluated in order to determine the feasibility of this system for electro-holography.
