Abstract
An experimental demonstration apparatus is described for projecting motion pictures in relief by application of the principle of the parallax panoramagram. A series of thirty-two posed, still pictures is made by the use of a large diameter concave mirror forming an image on a transparent concave ridged screen, which in turn is imaged on lantern-slide plates. Positives from these negatives are mounted on a slowly rotating disk in the slide plane of a projection lantern. A flashing mercury lamp illuminates each picture as it comes into position. The projected image is received upon the back of a translucent convex ridged screen. When viewed from the front, the moving picture changes its appearance with the observing position, and exhibits stereoscopic relief.
