PULSED LASER RANGING SYSTEM AND ITS MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a portable pulse-reflection-type laser ranging system having high reliability to disturbances.;SOLUTION: The portable pulsed laser ranging system 1 is provided with both an algorithm part 3 controlled by a microcontroller 2 for computing the distance X to an object 4 to be measured on the basis of a time difference τ between measuring pulses 6 and reference pulses 7 and a superimposition module 5 for computing time differences τ among a plurality of repetition pulse trains. The superimposition module 5 periodically performs superposition at a trigger frequency f_TRIGGER. The trigger frequency f_TRIGGER is made present within a frequency band of inequality 1 (wherein, m=1, 2, 3, etc.) every time a disturbance frequency f_STOR is equal to 100-120 Hz.;COPYRIGHT: (C)2006,JPO&NCIPI
