Paper Abstract

We propose an efficient calculation method to display three-dimensional information with purephase computer-generated holograms (CGHs). The object composed of points is conventionally divided into a set of planar segments vertically along with the axis. In this way, the number of planar segments is less than the number of points, which means that the total number of diffractions needed to calculate decreases. However, it is low efficient, for sometimes one planar segment only contains one point. We propose to quantize the locations of planar segments to solve this problem. The simplest way to quantize locations is to divide the object into the equal interval planar segments parallel with each other in the axis. The points out of these planar segments are projected to their nearest segments. Compared to traditional CGHs, the proposed method dramatically reduces the computing cost. Both simulations and experiments demonstrate the feasibility of the location quantization algorithm.
