LASER BEAM POINTING DEVICE Russian patent published in 2023 - IPC G02B26/10 

FIELD: optical-mechanical instrumentation.

SUBSTANCE: invention relates to optical-mechanical instrumentation, to devices for moving a laser beam in space, devices for optical scanning and tracking. The laser beam aiming device includes a fixed body on which an electric drive is fixed, a bearing, a hollow shaft rotating in the bearing with the help of an electric drive with a flat reflecting mirror mounted on it at an angle of 45 degrees to the shaft axis, the device is equipped with an annular angle sensor with a stator and a rotor, an electric drive contains an annular gearless motor with an annular stator and a rotor, the stators of the annular angle sensor and the annular gearless motor are rigidly connected to a fixed housing, and their rotors are coaxially fixed on a hollow shaft, while the shaft itself and the bearing associated with it, the motor and the sensor are entirely located under a flat mirror, the rear plane of this mirror is made transparent for the wavelength of the deflected laser beam, under it in the hollow shaft there is an absorber rigidly connected to the body of the part of the radiation that has not been reflected from the reflecting plane and passed through the flat reflecting mirror.

EFFECT: increasing the speed, accuracy and power of controlled laser beams.
