Patent ID: 8848172

Claim:
A handheld measuring device for optical distance measurement, comprising: a transmitting device configured to transmit periodically modulated optical measurement radiation toward a target object; a receiving device configured to detect optical measurement radiation returning from the target object; and an evaluation device configured to receive and evaluate detection signals of the receiving device; and a homogenizing device, wherein the evaluation device comprises a plurality of accumulation devices configured to accumulate detection signals, wherein the evaluation device conducts detection signals during a sampling time window from a plurality of sampling time windows temporally schematically changeably to an assigned accumulation device from the plurality of accumulation devices, such that the accumulation device accumulates the detection signals during the sampling time window, wherein the evaluation device determines a total signal acquired over a total measurement duration from the detection signals accumulated in the accumulation devices, and wherein said homogenizing device is configured to vary the temporally schematically changeable assignment of accumulation devices from the plurality of accumulation devices to sampling time windows during the total measurement duration.
