FIELD: optical engineering.
SUBSTANCE: optical deflector can be used in devices with optical-mechanical scanning of image for performing interlaced scanning. Optical deflector has framed mirror mounted onto base due to elastic member, piezoelectric ceramic bimorph member disposed in parallel to plane of mirror and supported as a cantilever onto the base. Free end of piezoelectric bimorph member is connected with peripheral area of mirror. Deflector additionally has restraint unit fastened onto mirror's frame and damping unit which has one end rigidly connected to the base. Free end of damping unit is connected with peripheral area of mirror through restraint unit and with free end of piezoelectric ceramic bimorph member mounted in restraint unit. Elastic member is connected with opposite peripheral area of mirror.
EFFECT: reduced load onto working end; improved vibration stability.
