Abstract

The invention relates to a method for reading out a computer-generated hologram (10). According to said method, a reading beam (4) is generated by means of a laser (2). The method according to the invention is characterized in that a diffuser screen (6) is used to diffuse the reading beam (4) and the surface of the hologram (10) is illuminated only with a part of the diffused reading beam (4).
