| 长度测量作为几何量测量关键共性基础技术之一，在科学研究、高端装备制造及空间探测等领域有着重要的应用。双光梳绝对测距技术充分发挥了光学频率梳的时域超短脉冲和频域高分辨特性，实现了高测量速率的绝对距离测量。目前双光梳测距存在测量范围小、测量精度低的问题，为解决此问题，提出了一种基于双光梳测距技术与相位测距技术相结合的方案，采用双光梳测距技术实现非模糊距离范围内长度的高精度测量，利用相位测距技术实现非模糊距离整数倍测量及指示功能，作为双光梳测距高精度测量的有效补充。搭建实验系统对该方案的可行性进行验证，结果表明在0~70 m的测量范围内，测量误差小于±5 μm。 |

| Length measurement, one of the key generic and basic technologies of geometric measurement, has important applications in scientific research, high-end equipment manufacturing and space exploration. The dual optical comb absolute distance measurement technology makes the best of the characteristics of the optical frequency comb in time domain ultra-short pulse and frequency domain high-resolution. Further it achieves absolute distance measurement with high measurement rate. Until now, the problems of limited measurement range and low measurement accuracy ail the community of double optical comb ranging. To relieve it, this work presents a novel technological solution, which combines the double optical comb ranging and phase ranging. The double optical comb ranging technology is adopted to realize the high-precision measurement of the length within the non-fuzzy range. The phase ranging technology is used to measure and indicate the integer multiple of the non-fuzzy range, which is an effective complement to the high-precision measurement of double optical comb ranging. An experimental system is built to verify the feasibility of the proposed technological solution, and the results show that the measurement error is less than ±5 μm within the measurement range of 0~70 m. |
