Speckle Noise Suppression Algorithm of Holographic Display Based on Spatial Light Modulator

Holography has emerged as one of the most attractive three-dimensional display technologies. With technological development computer science and coherent light source, computer-generated holography been applied in many fields. However, speckle noise holographic reconstructed image seriously affects viewing experience. In this paper, cause generation is introduced. Then, discussions about suppression methods are provided. The categorized into iterative non-iterative approaches. Besides, we also introduce other techniques which proposed from perspective coherence, human visual system optical system. Finally, prospects different types approaches summarized.
