Abstract

A handheld measuring device for optical distance measurement includes a transmitting device, a receiving device, an evaluation device, and a homogenizing device. The transmitting device is configured to transmit periodically modulated optical measurement radiation toward a target object. The receiving device is configured to detect optical measurement radiation returning from the target object. The evaluation device is configured to receive and evaluate detection signals of the receiving device. The evaluation device comprises a plurality of accumulation devices configured to accumulate detection signals. 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.
