Paper Abstract

The image width in cylindrical holographic stereograms has been limited to about one-third the diameter of the display drum. An analysis of the optical system shows that producing an image which fills two-thirds of the drum diameter or more requires a cylindrical lens with an f/number of 0.5 or smaller. Cylindrical lenses of such small f/number and adequate optical quality are not commonly available. These optical characteristics can be achieved readily, however, with a holographic element on a curved surface. A system designed for increasing image width making use of such a holographic lens is described. The requirement for an extremely low f/number cylindrical lens can be eliminated by another technique which involves curving the holographic film over a short radius platen. This technique is also described. It is shown that both these techniques compensate the nonlinear horizontal magnification distortion in cylindrical holographic stereograms.
