Claim:
1. A hand-held measuring device, for multi-dimensional measuring of a target object, comprising: a phase measuring system configured to carry out in sequence a measurement of a distance to individual object points of the target object; a transmission apparatus configured to emit optical measurement radiation toward the target object; a reception apparatus including a detection area configured to detect optical measurement radiation returning from the target object, the detection area having a plurality of pixels, each pixel of the plurality of pixels includes at least one SPAD; a scanning system configured to deflect the optical measurement radiation; and an evaluation apparatus configured to determine distance measurement values, every pixel of the plurality of pixels being connected to the evaluation apparatus, wherein the scanning system has a first galvano scanner for deflecting the optical measurement radiation emitted by the transmission apparatus toward the target object, wherein the scanning system has a second galvano scanner for deflecting the optical measurement radiation returning from the target object onto the reception apparatus, and wherein the first galvano scanner and the second galvano scanner are rotated synchronously about at least one axis.
