Abstract
The invention relates to 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 ( ) by means of an array ( ) comprising a plurality of apertures ( ), of a photodetector ( ) and of an evaluation circuit ( ). The laser light pulses entering each of the apertures ( ) and reflected by the target points ( ) are distributed in a preselected distribution ratio between at least two optical fibers ( to ) with an individual length which corresponds to a light travel time t , and are subsequently received by the photodetector ( ) and are processed in the evaluation circuit ( ). A unique assignment of the pulses to the respective apertures ( ) is rendered possible by their spacings, specified in accordance with the distribution, and amplitudes. The ranges of the target points ( ) can thereby be determined.
