Abstract:
1. A diffractor for modulating light incident thereon, the diffractor comprising: an electrically active substrate having an upper surface; a tent member disposed above the upper surface of the substrate and spaced apart in relation thereto and having a first planar light reflective surface formed on an upper side of the tent member the upper side facing away from the substrate, the first planar light reflective surface having an aperture formed therein; a movable actuator disposed between the upper surface of the substrate and the first planar light reflective surface, the movable actuator having a second planar light reflective surface parallel to the first planar light reflective surface and positioned relative to the aperture to receive light passing therethrough; and a mechanism for moving the actuator relative to the first planar light reflective surface of the tent member while maintaining the second planar light reflective surface substantially parallel to the first planar light reflective surface.
