Paper Abstract

A hologram generates a continuum of unique rays by means of wavefront reconstruction; but the eye is insensitive to phase, as such. Therefore, a holographic visual effect can be obtained by direct reconstruction of ray directions. This is the principle used in the Parallactiscope, a device which presents real-time CRT images having the holographic properties of autostereopsis and wide-angle (±45°) movement parallax. Viewer aids are not required, and multiple viewers are simultaneously accommodated; each viewer receiving a different pair of retinal images corresponding to his position. A working model of the Parallactiscope having a three-inch display has been built and demonstrated. A 14-inch model is now under construction.
