Abstract
Making multiplex holograms is not so popular in general laboratory because of its complicated optical system set-up and its costly optical components. But there are still many areas for multiplex hologram making and research, such as color multiplex hologram, flat multiplex hologram and multiplex hologram duplication. You cannot do the set-up just by try and error, since ways of optical components combination are so many and each component has so many specifications. You must get it well designed and then buy the components to build the system. Equations were derived to link the optical components for good imagery. A flow chart is developed. Based on it, a computer program can be written. With known film height and width of different formatted movie films, known distance from viewer to hologram, known distance from cylindrical lens to hologram, i.e., the radius of the cylindrical multiplex hologram, and with distance of cylindrical lens to spherical lens adjustable, you can get not only the specifications of the two main components, the large spherical lens and the cylindrical lens, but also all the other required parameters for the optical system set-up. Besides, optical paths of imaging are taken into consideration, horizontally and vertically. We believe, to multiplex hologram makers and researchers, it will help
