A new approach to computergenerated holography

A digital computer and automatic plotter have been used to produce a series of perspective views of a computer-stored three-dimensional object which is slightly rotated for each view. All of these views are combined together optically to produce a final hologram which can be viewed in high ambient light conditions. The reconstructed image appears three dimensional since each eye looks through a dif-ferent holographic strip corresponding to a different view of the three-dimensional object. The net result is a technique requiring only seconds of computer time and some possibly automated optical manipulations to produce extremely high quality holograms of computer-stored three-dimensional objects
