Measuring device for measuring a distance between the measuring device and a target object with the aid of optical measuring beam.

摘要

It is a measuring device (10) to the optical measurement of a distance to a target object (15) is described. The measuring device (10) has a transmitting device (12) for sending optical measuring radiation (13) on the target object (15), a receiving device (14) with a detection surface (66) for the detection of of the target object (15) back the course of the optical measuring radiation (16) and an evaluation device (36) on. The detection surface (66) has a plurality of pixels, wherein each pixel at least one spad (single photon avalanche diode) and wherein each of said plurality of pixels with the evaluating device (36) is connected. The transmitting device and the receiving device are designed in such a way that of the target object, the throughput of the optical measuring radiation of a plurality of pixels illuminated simultaneously. The evaluation device is designed in such a manner, a distance between the measuring device and the target object, based on an evaluation of detection signals to determine a plurality of pixels. Advantageously, at least some of the pixels in each case a plurality of spads, with the contained in a pixel number or area of spads on the basis of the location of the pixel can vary within the detection area.
