FIELD: optics.
SUBSTANCE: proposed converter designed for operation as actuating device in adaptive optical systems has multilayer stack of plates electrically connected in parallel with double-layer ferroelectric ceramic plate with diffused phase transition. One layer of double-layer plate has slot of depth equal to thickness of this layer. Axes of slots in adjacent double-layer plates are disposed in relatively perpendicular planes.
EFFECT: elongated travel distance of operating element, enhanced time and temperature stability.
