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.

Abstract: A laser distance measuring device for determining a distance to a target, in particular for a weapon system, comprises a first laser light source that is designed to emit laser pulses with a first pulse power, a second laser light source that is designed to emit laser pulses with a second pulse power, wherein the second pulse power of the second laser light source is higher than the first pulse power of the first laser light source (TX1), a receiver that is designed for receiving laser pulse radiation (RP) reflected by the target, an electronic controller for actuating the first laser light source, the second laser light source and the receiver. The electronic controller is designed to emit a first laser pulse by means of the first laser light source, after which, if a distance to the target cannot be determined with the first laser pulse by means of the receiver, a second laser pulse is emitted by means of the second laser light source.

Abstract: Radiation receiver with a photodetector and a sensor, wherein the sensor receives the radiation intensity, and a shutter arranged before the photodetector is driven in dependence on the detected incident radiation intensity. The incident radiation is supplied to the photodetector via a delay device arranged before the shutter, so that no radiation destroying the photodetector can reach the photodetector, due to the shutter having been driven, and can if necessary be kept away or absorbed by the shutter.
