采用光学频率梳的高精度绝对距离测量技术在航空航天、科学研究和工业生产等领域都发挥着重要作用. 提出一种利用光学频率梳技术，通过检测光强实现绝对距离测量的新方法，研究了光学频率梳发出脉冲的时间相干性，分析了光强与被测距离之间的关系、干涉条纹峰值点位置与被测距离之间的关系. 建立了基于Michelson干涉原理的测距系统，通过测量光强信息得到被测距离. 以高精度纳米位移平台的位移量作为长度基准进行了绝对测距实验，在每个被测距离点都重复进行了10次实验，将10次实验测得的光强值取平均后用于距离的计算. 实验结果表明，该方法可以实现绝对距离测量，在10 μm测量范围内，最大误差为47 nm. 因此，该方法可以应用于大尺寸高精度的绝对距离测量.High-accuracy ranging system is of significance both in future space-based sciences and in large-scale manufacture. Based on the light intensity, a method of measuring absolute distance in a long range by using the optical frequency comb is demonstrated. The temporal coherence of the pulses emitted from the optical comb is analyzed. The measurement principle is introduced. The peak position of the interference fringe is analyzed, which can contribute to the distance measurement, and numerical simulations are also developed correspondingly. The experimental results show that the absolute distance measurement can be realized. This method can be used to measure a large-scale distance.
