Abstract

During recent years, research in the area of computer generated holography (CGH) almost exclusively dealt with the improvement of the algorithms to produce CGHs with enhanced performance. Now we would like to concentrate on improvements of the CGH quality by using certain tricks during the actual manufacturing process. In most CGHs the sampling cells contain one or sometimes two black rectangles. The size of the rectangle is responsible for the local light amplitude. The location of the rectangle determines the phase of the light, which is diffracted at that cell.
