  • Apparatus for determining the angle of incident electromagnetic radiation
    Patent number: 4270048
    Abstract: Apparatus for receiving electromagnetic radient energy is disclosed, inclng a radiation detection element, a movable optical element for directing the radiation toward the detection element, and a drive system for automatically adjusting the position of the optical element to cause the radiation to always be directed toward the detection element. The drive system includes a pivotally mounted permanent magnet connected with the optical element, a plurality of coils arranged circumferentially about the magnet, and radiation-responsive control circuit for selectively energizing the coils to produce a magnetic field that displaces the magnet and the optical element to maintain direction of the radiation upon the radiation detection element.
