The advent of femtosecond optical frequency comb (FOFC) has a significant influence on time-frequency technique and spectroscopy, so that the derivative technique for absolute distance measurement by FOFC, which features in an advantage of high-speed, large-scale and high-precision, has become a worldwide research hotspots and is promising to be directly applied in some precision ranging missions, such as large equipment manufacturing, satellites formation flying and laser radar. Based on a brief introduction of basic theory and main application for FOFC, the development history and the cutting-edge study for FOFC ranging are introduced, and the newest progress in FOFC large-scale precision ranging in most recent years are emphatically introduced as well. A summary and outlook about FOFC ranging is given finally.
