Abstract
In this paper, we present a fast hologram pattern generation method by radial symmetric interpolation. In spatial domain, concentric redundancy of each point hologram is removed by substituting the calculation of wave propagation with interpolation and duplication. Also the background mask which represents stationary point in temporal domain is used to remove temporal redundancy in hologram video. Frames are grouped in predefined time interval and each group shares the background information, and hologram pattern of each time is updated only for the foreground part. The effectiveness of proposed algorithm is proved by simulation and experiment.
