Comparison of Stereograms: Pinhole, Fly’s Eye, and Holographic Types*

This paper evaluates the effect of system parameters on resolution of the three stereographic methods and excludes discussion of the stereographic effect. Pinhole-camera stereogram imagery is shown to have several severe deficiencies, among which are the need for small camera-to-object distances and poor filling of the ray cones. The fly’s-eye lens is much superior, but these images are severely degraded by aberrations. The holographic stereogram overcomes these problems but is a slower process. A wide-angle eyepiece is demonstrated as a practical camera lens for recording the component images of the holographic stereogram.
