- Archival storage of color images and pseudocoloring of black and white images have received considerable interest in the last hundred years. This dissertation is a theoretical and experimental study of archival storage and pseudocoloring, which is based on recent progress in optics and computer technologies., Since a white-light source contains all the visible wavelengths of light, a white-light optical processor has inherent advantages for processing color images. In this dissertation, a white-light processor is used for two methods of color image storage and several applications of pseudocoloring., A three-step archival storage method is reviewed, then a one-step method is proposed for recording color information on a monochrome transparency using a linear tricolor sampling pattern. It is shown that the method avoids moire fringes, color-cross-talk, and is free from coherent artifact noise. The linear tricolor sampling pattern is described in detail and a method for computer generation of the tricolor grating is presented. Color images retrieved using the tricolor grating show that the method is a viable alternative to previous three-step encoding methods. Furthermore, future research may enable us to create a new color image storage and display system by using black and white film rather than color film., The method of density pseudocolor encoding with three primary colors is simple, versatile, and economical to operate. Many colorful experimental results demonstrate that the method can be used in many fields of scientific research. Also, a computer controllable decoding system is discussed, which makes the operations of archival storage and pseudocoloring more flexible., and The study of coherence properties of the system suggested that an incoherent system would be applicable to archival storage and pseudocoloring. This dissertation presents an incoherent processing system with experimental results.
