OPTICAL DEFLECTOR Russian patent published in 2007 - IPC G02B26/00 

FIELD: the invention refers to optics-electron instrument-making industry and may be used in arrangements with optics-electron -mechanical scanning of image for execution for example of interlace scanning.

SUBSTANCE: the essence of the invention is in an optical deflector having a mirror with a setting mounted on a foundation with possibility to rock on an elastic suspension, a piezoceramics bimorph element located in parallel to the plane of the mirror and cantilevered on the foundation, the free end of the piezoceramics bimorph element is connected with the periphery zone of the mirror, the elastic suspension is fulfilled in the shape of two pairs of flat springs located from the opposite sides of the mirror symmetrically relatively to the longitudinal axis of the piezoceramics bimorph element, the flat springs in each pair are installed symmetrically relatively to the axis of rocking of the mirror under the angle of 90⁰±10⁰ relatively to each other. At that the line of intersection of the planes of the installation of flat springs coincides with the axis of rocking and passes through the center of the masses of the mirror with the setting.

EFFECT: increases frequency of the own vibrations of the mobile part of the deflector.
