采用镀金玻璃盖板制作了双光纤激光器梳状结构的激光雷达系统。研究结果表明，在1.09m的距离上，飞行时间法测距精度为0.4 μm，平均时间为0.4s，无模糊距离为2.1m。该系统具有1 kHz的更新速率和较大的非模糊范围，适用于制造或加工应用中的绝对距离测量。
We employed a gold coated glass cover plate to fabricate dual compact free running fiber laser combs based LIDAR (light detection and ranging) system with tunable difference of repetition rates. Our study shows that the ranging precision is 0.4 μm and the non-ambiguity range is 2.1 m with averaging time of 0.4 s for the distance of 1.09 m by the time-of-flight method. The system with 1 kHz-high update rate and the large non-ambiguity range is potentially useful for manufacturing or machining application applied in absolute distance measurement.
