PIEZOELECTRIC SINGLE-MIRROR TWO-AXIS OPTICAL DEFLECTOR Russian patent published in 2017 - IPC G02B26/08 

FIELD: optics.

SUBSTANCE: invention relates to optics, particularly, to optical devices for control over position and direction of optical beams in space and can be used in optical information-measuring systems. Piezoelectric single-mirror two-axis optical deflector consists of housing, mirror in holder, two hinges, central base, actuating drives, heels, pushers, sensors and control system. First hinge is made in form of flat torsion spring, one end of which is secured on holder with mirror, other is on central base, second hinge is also made in form of flat torsion spring, one end secured on central base, and other is on housing. Second hinge is arranged perpendicular to first hinge.

EFFECT: technical result is simplification of design while maintaining fast operation speed, accuracy during mirror deviation angles development, reliability and reducing device weight and overall dimensions.
