Suppression Effect of Randomly-disturbed LC Alignment Fluctuation on Speckle Noise for Electronic Holography Imaging

SUMMARY In this paper, we proposed the phase disturbing device using randomly-fluctuated liquid crystal (LC) alignment to reduce the speckle noise generated in holographic displays. Some parameters corresponding to the alignment fluctuation of thick LC layer were quantitatively evaluated, and we clarified the effect of the LC alignment fluctuation with the parameters on speckle noise reduction.
