| Abstract: | The main limitation of a Intensity Modulated Continuous Wave laser rangefinder is the leakage distortion created by the high frequency current source which modulates the laser diode. In this paper, this leakage distortion is studied systematically, the cause of the distortion and its relationship with the measurement accuracy are analyzed, the calculation equation and compensation of the error caused by this distortion are given. |
