Abstract
Very large bandwidths are required for the transmission of holographic data for systems such as TV. This paper presents a technique in which the large bandwidths normally required are traded off for either increased noise or decreased resolution in the image. The light radiated from the object is diffracted by an intermediate dispersion medium and collected at the hologram aperture. Correct illumination of this hologram provides an image beam that passes back through the intermediate medium and comes to focus in the space originally occupied by the object. By proper selection of the dispersion medium, the hologram aperture can be made extremely small, thus representing a large data reduction. The three dimensionality of the image and the original viewing angles are maintained. Included in the paper are experimental results that show reconstructed images after a data reduction of as much as 3600.
