Paper Abstract

Hologram generation by means of computers has been developed during the last three decades. The most frequently used methodology is the Fourier method. However, these techniques are not completely adequate to obtain holograms for 3-D display. A method of calculating holograms of parametric curves and surfaces is presented. These holograms are well suited to 3-D display although, in practice, their size is small. Holograms are obtained regardless of the position and the size of the object. Furthermore, the effects of the intermodulation noise are theoretically eliminated by cancelling the corresponding terms in the expression of the hologram. Thus, this technique is easily extended to combinations of curves or surfaces. Calculations can be carried out using suitable numerical approximations. Although the method is quite general, results are presented for linear segments. One example of a linear segment hologram has been represented on a computer screen. After photo-reduction, the segment has been successfully reconstructed.
