LIGHT BEAM DEFLECTION DEVICE Russian patent published in 2010 - IPC G02B26/08 

FIELD: physics, optics.

SUBSTANCE: invention relates to optomechanical industry and can be used in different optoelectronic devices for controlling spatial position of a light beam. The device for deflecting a light beam has a housing in which two supports are mounted on a shaft on which a mirror is mounted. The mirror actuator is in form of a stator and a rotor and is mounted at one end of the shaft. The stator is made from four coils connected in series and arranged around the rotor. The coils are displaced from each other by 90°. The coil cores are in form of permanent magnets. One pair of coils is wound in one side and the other in another side in the direction of flow of current. The rotor is made in form of a quadripolar armature with a device for controlling its angular position mounted on the shaft. The rotor is made from magnetically soft material. The device for controlling angular position of the quadripolar armature is in form of a capacitive sensor.

EFFECT: reduced power consumption by the device.
