Abstract
A single crystal bender actuator for selectively positioning a movable precision optical or acoustical component is described which comprises a single crystal of barium titanate, barium strontium titanate, barium lead titanate, potassium niobate tantalate, lead titanate-lead magnesium niobate or other material in which a special domain structure can be induced to produce a very high strain bimorph configuration, the single crystal operatively interconnecting support structure and the movable component, and means for selectively applying an electric field of controllable field strength to the crystal.
