説明
It takes long time to calculate computer generated hologram due to a large amount of computation for light difraction of object light. In this paper, we propose a new fast algorithm for object-light calculation using patch model for computer generated Fourier hologram. The precalculated fringe pattern from a basic patch is transformed to one of each patch by slide & rotation, distance, slanting and magnification transforms. The results of computer simulation and optical experiments show that the transforms are applied to computer generated hologram successfully and the method is about 60 times faster than traditional method.
