Paper Abstract

An electro-holographic display based on the diffraction specific computation can reduce speckle using electronic diffusion through selective addition of pseudorandom sequence. Intensity fluctuation due to the introduction of pseudorandom noise does not affect 3-D images significantly since spatial windows formed by diffused basis phase sets do not widen noticeably at low spread of the pseudorandom sequence while its features are much smaller than human visual resolution. The result shows crosstalk blur characteristic of substantial variation in the degree of diffusion among basis phase sets. Also, coherent artifacts may be produced by the interference between spatial windows if basis phase sets are sub-optimally designed.
