Speckle Reduction in Holographic Displays

摘要

Speckles, resultant to the randomized interference of coherent fields, are inherent in holographic displays. Speckle in holographic displays leads to low signal-to-ratio in the reconstructed holographic images and causes potential eye-safety issues. In this invited paper, recent works on speckle reduction in holographic displays either by modulating the light source module or by temporally multiplexing the computer generated holograms will be introduced.
