LASER SCANNING DEVICE Russian patent published in 2009 - IPC G02B26/10 

FIELD: instrument making.

SUBSTANCE: invention is related to optical-mechanical instrument making, in particular to devices for displacement of laser beam in space, scanning and tracking devices. Laser scanning device comprises directional source of radiation installed opposite to mirror fixed on quadriradiare crosspiece, and system of mirror control, which are assembled in body, moreover, system of beam deviation is additionally equipped with four guide rods fixed one by one on each of four crosspiece ends. Each guide rod is connected to crosspiece with the help of hinged joint, having four freedoms. Guide rods have angular thread on their external surface, with the help of which they are fixed in immobile threaded bushes with similar internal thread, and have the possibility to move reciprocally in process of rotation to this or that side. And control elements used are electric motors that rotate guide rods.

EFFECT: higher accuracy and variation of functional resources to produce complex trajectories of laser beam movement.
