  • Wide-angle infrared cloud imager
    Patent number: 5585632
    Abstract: A wide-angle infrared cloud imager that comprises a first and second mirrors driven by first and second stepping motors is disclosed. The first and second mirrors are rotated by the steps motors at axes orthogonal to each other. The first mirror directs reflected infrared radiation to the second mirror. Infrared radiation reflected from the second mirror is directed to an infrared radiation detector that outputs a signal directly proportional to the intensity of incident infrared radiation. The signal is provided to a computer for recording. The computer also provides the driving signal to drive the first and second motors.
