SYSTEM FOR CORRECTING ERROR OF LASER REFLECTION SIGNAL LEVEL FLUCTUATION AND METHOD THERE FOR

摘要

PURPOSE: A system for correcting error of laser reflection signal level fluctuation and method therefor are provided to minimize the error of the reflective signal by correcting the phase difference between signals due to the delay time. CONSTITUTION: The laser output module(110) radiates the laser signal for measuring distance to the object. The reflective signal receiving module(120) changes digital by receiving the reflective signal reflected from the object. The reflective signal hybrid module(130) draws the amplitude coefficient. The amplitude conversion module(140) draws the second delay times by overlapping the trigger signal according to the amplitude coefficient. The phase difference measurement module(150) draws the phase difference between 3K reflective signal and the standards reflective signal. The reflective signal correction module(160) corrects the phase of the standards reflective signal and 3K reflective signal.
