Abstract

This stereoscopic photography system produces panoramic 3-D images viewable without glasses, to eliminate the window effect. Such causes the image to appear as though it were being viewed through a distant window, and to widen the ordinary narrow angle of view of 30 degrees to 40 degrees. Holograms are used as the recording mechanism. Images in 3-D can be viewed without glasses. In drawing 1, panoramic 3-D view is achieved by making hologram 10, on 16 mm. frames, of a scene projected by lens 12 inside hemisphere 14, one scene for each eye.

Panoramic Lensless Stereoscopic Viewing System

This stereoscopic photography system produces panoramic 3-D images viewable without glasses, to eliminate the window effect. Such causes the image to appear as though it were being viewed through a distant window, and to widen the ordinary narrow angle of view of 30 degrees to 40 degrees. Holograms are used as the recording mechanism. Images in 3-D can be viewed without glasses. In drawing 1, panoramic 3-D view is achieved by making hologram 10, on 16 mm. frames, of a scene projected by lens 12 inside hemisphere 14, one scene for each eye.

When these holograms are viewed by the corresponding eyes, the hemispheres are recreated for each eye just as if the complete hemispheres were physically present. Thus, complete, panoramic view of any scene can be viewed in 3-D by looking directly through a 16 mm. film strip 20 without lenses as in drawing 2.

A characteristic of holograms is that the image formed can be viewed only when illuminated from the same angle as the original reference light. In this system, the right eye image of one scene can be superimposed upon the left eye image of the next scene. Thus, in drawing 3 on strip 30, the same frame 32 contains two images. The left eye image is seen by light beam 34, directed to the left, the right eye image by light beam 36, directed to the right, by beam splitter 36. Three-dimensional panoramic movies can be made by the proper movement of film strip 30.
