ABSTRACT

This chapter focuses on color image display with black-and-white film utilizing a tricolor grating. A large amount of color information must be stored for display in the future. As a permanent storage material, the multilayered color film made of organic dyes is not an ideal candidate. To directly produce a faithful color image on color print paper, a complementary color image should be formed at the output plane of the decoder. The principle of complementary color production is based on the implication that the tricolor grating has a minimum transmittance greater than zero. The color image display system can be constructed with simple optical elements. An alternative white-light processing scheme used in the optical demonstration consists of a single lens. The input and output planes are arranged to be conjugate planes. The tricolor grating is the key optical element for color image encoding, and its quality will influence the application of this technique.
