Abstract
The disclosure relates to a measuring apparatus, in particular a handheld measuring apparatus, for measuring a target object in a multidimensional manner, wherein the distance to individual object points of the target object is sequentially measured, in particular using a phase-measuring system, which apparatus has at least: a transmitting device for emitting optical measuring radiation towards the target object; a receiving device having a detection area for detecting optical measuring radiation returning from the target object; a scanning system for deflecting the optical measuring radiation, and an evaluation device for determining measured distance values. The detection area of the receiving device has a plurality of pixels, wherein each pixel has at least one SPAD, and wherein each of the plurality of pixels is connected to the evaluation device. The disclosure also relates to a measuring device having such a measuring apparatus.
