- Abstract
Three-dimensional displays of anatomical structures and clinical findings are very persuasive and instructive. Using multiplex holograms, we designed a display of three-dimensional images of otological specimens. Multiplex holograms, reported by Cross of the United States in 1975, enable reconstruction of three-dimensional moving images and are used for artistic display as well as for teaching in medicine and general education. Multiplex holograms were recorded in a two-step process. The first step is to make a series of original cine-pictures of an object from different horizontal directions, rotating it on a turntable. In the second step, one frame of the original film is recorded on a narrow strip hologram. All frames of the original film are recorded one after another and a complete multiplex hologram can be synthesized. In the reconstruction stage, the multiplex hologram is formed into a cylinder and illuminated from below by a small white light source. Reconstructions of the three-dimensional bright images of the object inside the cylindrical holographic screen are shown.
