Abstract
A spatial light modulator (SLM) is disclosed that increases speed and efficiency of an SLM through the use of a perforated hinge. The hinge may take many forms, but generally includes an elongated body having holes therein along its longitudinal direction. One or more electrodes are charged with a predetermined voltage in order rotate a reflecting surface towards the electrodes through electrostatic attraction. The perforations within the hinge results in the hinge being made from less material so that it is less sensitive to hinge thickness variations that can occur during the manufacturing process. Consequently, the perforated hinge allows for more stable, uniform mirror rotation.
