Abstract

A measurement device for measuring an optical distance of an object includes an emission device configured to emit a first signal towards the object. The measurement device further includes a modulator device configured to modulate the first signal and a reception device configured to detect a second signal. The measurement device also includes an analysis device configured to receive and analyze the second signal. The measurement device further includes a calibration device configured to calibrate the measurement device with the modulator device turned on and with the emission device operated below a pre-definable power threshold value.
