Abstract
A liquid-crystal (LC) spatial light modulator for hologram synthesis consisting of a high resolution twisted nematic LC-panel of active matrix type has been developed. Output images with signal-to-noise ratio of 30 dB and maximum contrast ratio over 600 were obtained. The stability of the displayed image was analyzed on the basis of two beam interferometry. Confirmation of no appreciable degradation in diffraction efficiency was obtained.
