Averaging Time

We employed a gold coated glass cover plate to fabricate the dual compact free running fiber laser combs. It had been used for a difference of repetition rates tunable LIDAR (light detection and ranging) system. 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. The system with 1 kHz-high update rate and the large non-ambiguity range is potentially useful for manufacturing application applied in absolute distance measurement.

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.
