Paper Abstract

Different techniques for making digital holograms in order to synthesize true 3D images have been reported. The generation of digital Fresnel holograms by means of the ray- tracing method is the most flexible way and relatively simple, that is the objects are considered to be composed of a large number of discrete points sources of light, and the complex amplitude of spherical waves from each point sources is super-imposed on the hologram plane, however there is carry out a great amount of calculate. We presented a technique in order to evaluate simultaneously eight points on the hologram plane, so we obtain a reduction in a factor of eight the computation time. The equation of Kirchhoff- Fresnel is first calculated applying symmetry conditions avoided the redundancy in the calculations and later added the reference wave; also the precision in the values of the complex amplitude is not loss. Other methods that have been reported coupled components doing the ray tracing methods quicker yet.
