An Experimental Apparatus for the Projection of Motion Pictures in Relief

Herbert E. Ives

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.
