A scheme is presented that permits a continuous view of an image displayed on a dc-balanced ferroelectric liquid-crystal-on-silicon spatial light modulator. I develop the theory and present experimental results, using a 256 × 256 ferroelectric liquid-crystal-on-silicon spatial light modulator. It is shown that both halves of the dc-balanced cycle can be made to produce identical outputs even when the illumination is polychromatic and the spatial light modulator liquid-crystal layer thickness is not an ideal half-wave plate and for an arbitrary liquid-crystal switching angle.
