Hand-held pulse laser distance measuring device

摘要

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 (tau) between a measurement pulse ( 6 ) and a reference pulse ( 7 ) and with a superimposition module ( 5 ) which calculates the time difference (tau) of a plurality of repeated pulse trains which are periodically superimposed with a trigger frequency f_TRIGGER, wherein the trigger frequency f_TRIGGER lies in the frequency range of $0.7.\frac{2}{2.m-1}.f_{\mathrm{INT}}<f_{\mathrm{TRIGGER}}<1.3.\frac{2}{2.M-1}.f_{\mathrm{INT}},\mathrm{where}m=1,2,3,\mathrm{...}$ at an interference frequency f_INT=100 Hz . . . 120 Hz; and a measuring method for the pulse laser distance measuring device.
