Zusammenfassung:	For passive range metering of moving vehicles a receiver is used having two detectors spaced apart and directed to the path of the vehicle which moves with constant speed and the length of which is known. The receiver measures the pass-through time of the image of the vehicle through the first detector and furthermore measures the traveling time of the image of the vehicle from one detector to the other. The distance E can be calculated by equation wherein f is the focal distance of the receiver optics, Qt is the quotient of the measured time values, l is the length of the vehicle.
