Abstract
A hand-held pulse laser distance measuring device () with an algorithm () which controls a microcontroller () and which serves to calculate the distance (X) to a measurement object () by a time difference (τ) between a measurement pulse () and a reference pulse () and with a superimposition module () which calculates the time difference (τ) of a plurality of repeated pulse trains which are periodically superimposed with a trigger frequency f, wherein the trigger frequency flies in the frequency range of at an interference frequency f=100 Hz . . . 120 Hz; and a measuring method for the pulse laser distance measuring device.
