Abstract
Computer-generated holograms of a diffused object can be generated as the sum of intensity holograms obtained by interference of each point of the object with the reference beam. Thus the intermodulation noise is avoided. According to this, the authors have obtained computer- generated holograms of a square diffused object, and they were represented in a computer screen. By means of a photo-reduction process, they were stored in an emulsion 8E56 HD. The diffraction effiency (DE) and the signal-to-noise ratio (SNR) was evaluated in the reconstructed real image. A DE of 1% and a SNR of 100 have been obtained.
