Abstract

Computer generated holograms are designed starting with the images of the desired objects, which will be formed on a screen, after laser diffraction on the holograms. In the design step, these digitized images are placed inside the signal window. We analyzed the influence of the size and the position of the signal window on the parameters values of the diffracted intensity distribution (diffraction efficiency and uniformity). First, we considered simple objects (three points and a line with a given size) and then an object of a logo type. The distance between the hologram plane and the image plane was also preset. Simulation and experimental results are presented.
