HOLOGRAPHIC IMAGE SYNTHESIS UTILIZING THEORETICAL METHODS

A theoretically calculated, automatically plotted, and photoreduced hologram has been successfully used to ``reconstruct'' the image of a nonexistent, three‐dimensional, equilateral tetrahedron. The theory, as presented therein, provides a synthetic hologram which consists only of completely opaque and transparent portions; allows reconstruction of the entire image with any fraction of the hologram as in conventional experimental types; can be made to reconstruct objects for either on‐ or off‐axis viewing; provides both a real and virtual image; and produces a positive image with both positive and negative prints.
