Paper Abstract

Recently, N-LUT method to dramatically reduce the number of pre-calculated interference patterns required for generation of digital holograms was proposed. In this method, the fringe patterns for other object points on each image plane can be obtained by simply shifting this pre-calculated PFP according to the displaced location values from the center to those points and adding them together. Accordingly, CGH pattern for arbitrary line is shifted with amount of discretization step for the direction of next line, same images for arbitrary line are generated in the next line. And then differences between two lines are occurred, these differences are compensated in CGH pattern using the N-LUT method. Accordingly, in this paper, a new approach for fast computation of CGH patterns for the 3-D image by taking into account of the line-redundancy between lines of the 3-D image is proposed. Some experiments with a test 3-D object are carried out and the results are compared to those of the conventional methods.
