Paper Abstract

Parallactiscopes (parallactic oscilloscopes) produce holoform (hologram-like) images in real time by reconstructing ray directions with a horizontally-scanned vertical slit. The slit causes each narrow vertical zone on the CRT screen to be keyed to a unique viewing direction, thus presenting a different total image to each of the many eyes of a group of observers. As a direct result of the process, stereo and movement parallax are produced automatically and without any observer constraints or observer-worn hardware being necessary. Solid models (opaque images) can be displayed as well as wire-frame (transparent) models. Viewing angles up to ±45 degrees off axis are readily accommodated. This paper describes the latest in a line of parallactiscopes designed, built, and demonstrated by the author. It incorporates a 19-inch electrostatically-deflected CRT.
