ABSTRACT:
A hand-held pulse laser distance measuring device (1) with an algorithm (3) which controls a microcontroller (2) and which serves to calculate the distance (X) to a measurement object (4) by a time difference (τ) between a measurement pulse (6) and a reference pulse (7) and with a superimposition module (5) which calculates the time difference (τ) of a plurality of repeated pulse trains which are periodically superimposed with a trigger frequency fTRIGGER, wherein the trigger frequency fTRIGGERlies in the frequency range of0.7·22·m-1·fINT<fTRIGGER<1.3·22·m-1·fINT,wherem=1,2,3,…at an interference frequency fINT=100 Hz . . . 120 Hz; and a measuring method for the pulse laser distance measuring device.
