Simulation of a holographic 3-D television display

The theory and the computer simulations of an acousto-optical holographic 3-D television display are presented in this dissertation. The technique used is based on the reproduction of the desired pattern, in our case the hologram, using traveling surface waves. The crystal that will be used as the medium of display is assumed to have a number of electrodes attached to it on one side. If signals are applied to all of the electrodes, propagating waves from the electrodes will superpose to form a time-varying surface field pattern on the crystal. It is possible to find out the signals to be applied to the electrodes through an inversion relationship from the original holographic pattern. The proposed method is simpler and more efficient than the methods available in the literature and it solves the display resolution problem completely.
