Abstract

A measuring device for optically measuring a distance to a target object includes an emitter device for emitting an optical measuring beam to the target object, a capturing device including a detection surface for detecting an optical beam returned by the target object, and an evaluation device. The detection surface has a plurality of pixels, each pixel having at least one SPAD (single photon avalanche diode) and each of the plurality of pixels is connected to the evaluation device. The emitting device and the capturing device are configured in such a manner that the optical measurement beam returned by the target object simultaneously illuminates a plurality of pixels. The evaluation device is configured in order to determine the distance between the measuring device and the target object based on the evaluation of detection signals of several pixels.
