<p>A spatial light modulator formed of a moveable electrode (30) which is disposed opposite a fixed electrode (12) and is biased to roll in a preferred direction upon application of an electric field across the electrodes to produce a light valve or light shutter. In one embodiment, the moveable electrode is restrained at one end and coils about the fixed end in a preferential roll direction. The bias is achieved by inducing anisotropic stress or anisotropic stiffness.</p> |
