Time fluctuations of the phase modulation in a liquid crystal on silicon display: Characterization and effects in diffractive optics
In this paper we provide evidence of the temporal fluctuations of the phase modulation property of a liquid crystal on silicon (LCoS) display, and we analyze its effect when the device is used for displaying a diffractive optical element. We use a commercial twisted nematic LCoS display configured t...
