A multiplex hologram is synthesized by using a special optical system from an original film composed of a series of conventional photographs taken from different horizontal directions. An automatic apparatus for synthesizing multiplex holograms is built and fundamental properties of reconstructed images such as distortion and resolution are studied for both ordinary and medical objects. Some techniques to compensate the distortion are developed.© (1985) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.

An approximate treatment of partially coherent image formation is applied to projection systems, and it is concluded by both theoretical and experimental studies that the image-forming performance in this case can be treated as a special case of incoherent imagery characterized by the “stopping effect” of the effective source. The practical definition of effective source and the influence of the condenser's aberration on the image are also considered.
