  • Electro-optic space positioner with background compensator
    Patent number: 4840069
    Abstract: The output of a diode array undergoes A/D conversion. A constant digital value is added to the output when remote light sources remain de-energized to establish an ambient threshold level. The remote sources are then energized; and when a digital array output signal is sensed at a level exceeding the threshold, the positive existence of a sensed source is established. The invention has application in the measurement of aircraft wing vibration.
