摘要

Phase error compensation is necessity for high resolution optical frequency modulated continuous wave (OFMCW). In the phase error compensation of OFMCW, the precise measurement of laser source phase is the most significant. In this paper, we proposed a phase-smooth unwrapping algorithm to settle the issue of phase leap over 2π, thus could restore precisely the real phase of laser source, then could compensated the phase error in OFMCW. With that method, OFMCW's resolution could be promoted to 0.5 mm at over 200 m.
