Piezoelectrically Bendable Mirrors For Spatial Modulation Of LightFlexible mirrors including multiple small piezoelectric actuators (bimorphs) attached to back surfaces developed. Weigh less, respond faster, actuated by lower voltages, and include larger numbers of bending actuators for finer control of surface contours. Mirrors used as spatial light modulators in optical computers, to compensate for atmospheric distortions in astronomical telescopes, and in other applications in which wave fronts altered controllably.
