Multichannel receiver system for angularly resolved laser ranging measurement
Abstract:
The invention relates to a multichannel receiver system (1) for angularly resolved laser ranging measurement, in which a laser light pulse from a laser (7) using the pulse travel time method is used to measure the ranges of a plurality of target points (6) by means of an array (2) comprising a plurality of apertures (3), of a photodetector (9) and of an evaluation circuit (10). The laser light pulses entering each of the apertures (3) and reflected by the target points (6) are distributed in a preselected distribution ratio between at least two optical fibers (511 to 543) with an individual length which corresponds to a light travel time tn,m, and are subsequently received by the photodetector (9) and are processed in the evaluation circuit (10). A unique assignment of the pulses to the respective apertures (3) is rendered possible by their spacings, specified in accordance with the distribution, and amplitudes. The ranges of the target points (6) can thereby be determined.
