CONTINUOUS VIEW OF DC-BALANCED IMAGES ON A FERROELECTRIC LIQUID-CRYSTAL SPATIAL LIGHT-MODULATOR

A scheme is presented that permits a continuous view of an image displ ayed on a de-balanced ferroelectric liquid-crystal-on-silicon spatial light modulator. I develop the theory and present experimental results , using a 256 x 256 ferroelectric Liquid-crystal-on-silicon spatial li ght modulator. It is shown that both halves of the do-balanced cycle c an be made to produce identical outputs even when the illumination is polychromatic and the spatial light modulator liquid-crystal layer thi ckness is not an ideal half-wave plate and for an arbitrary liquid-cry stal switching angle.
