摘　　要：飞秒光学频率梳的出现对时间频率技术和光谱学技术产生了深远重大的影响,由此衍生的飞秒光学频率梳绝对测距技术以其快速、大尺寸、高精度等优点已成为国际研究热点,并有望直接应用于大装备制造、激光雷达和卫星编队飞行等大尺寸精密测距。在简要阐述飞秒光学频率梳的原理特性及主要应用的基础上,围绕光梳测距的发展历程及前沿方向,着重介绍了飞秒光梳精密测距近两年来的最新研究进展,并对该技术进行了总结和展望。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 fly- ing 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.
