Abstract:
A multichannel receiver system for angularly resolved laser ranging measurement, in which a laser light pulse from a laser using the pulse travel time method is used to measure the ranges of a plurality of target points, the system comprising:an array comprising a plurality of apertures; a photodetector; an evaluation circuit; and wherein laser light pulses enter each of the apertures after being reflected by said target points and are distributed in a preselected distribution ratio between at least two optical fibers with an individual length which corresponds to a light travel time tn,m, and wherein said laser light pulses are subsequently received by said photodetector and are processed in said evaluation circuit, and wherein a unique assignment of the pulses to said respective apertures is rendered possible by respective spacing of said laser light pulses and, said laser light pulses are specified in accordance with the distribution; and respective amplitudes wherein it is possible to determine the ranges of said target points.
