Abstract: Disclosed are a pair of light intensity detectors spaced apart in range. Included is an arrangement for reflecting light from a target to each detector and maintaining the intensity of the reflected light detected by one detector constant whereby the output signal of the other detector is a measure of range. Included is an arrangement for processing, linearizing and displaying the signal representing target range. The system disclosed employs the method of reflecting electromagnetic energy of varying intensity from a target to maintain the intensity of reflected energy at one position constant while monitoring intensity at a second position to measure range.
