Abstract

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.

Fig. 1.

Photographs of part of the SLM array showing images in (a) the first and (b) the second halves of the cycle. One line on the device is not functioning correctly, which shows up as appearing distinctly different in the two halves of the cycle. The second half of the cycle has reduced contrast, as in this half of the cycle front face reflections from a damaged antireflection coating on the SLM are not eliminated by the output analyzer.
