Description

We have already proposed the holographic display technique that sequentially generates a number of elementary holograms in order to enlarge the image size and the viewing zone angle. The elementary holograms displayed by a high-speed spatial light modulator are scanned horizontally by a galvano mirror. In this paper, a calculation method of the elementary holograms is described. Under the actual situations, the inconsistency in reconstructed images of the elementary holograms causes blurs in reconstructed images and the image quality is deteriorated. Horizontal positions and pixel pitches of the elementary holograms are measured in advance, and are used for the calculation of elementary holograms. The distance between a horizontal light focusing point to a screen is experimentally determined. Consequently, image blurs are reduced and the image quality is improved.
