Abstract

The existence of the end face reflection in the collimator lens seriously affects the performance of coherent Lidar based on phase-modulated continuous wave (PMCW). We present an algorithm to eliminate the end face reflection basing on its characteristic of periodic digital modulation. Ultimately, with this algorithm, the effective distance is increased to 90m when the emitted optical power is 50mw.
