High-precision short-distance dual-comb ranging system without carrier-envelope-offset locking

Y Yang, S Qian, S Zhou, G Wu - Optics Express, 2024 - opg.optica.org
In this paper, we propose a high-precision dual-comb ranging (DCR) method for short-
distance measurement, avoiding carrier-envelope-offset locking. Cross-polarization …

Absolute distance measurement without dead zone based on dual-channel dispersive interferometry using the femtosecond laser

X Liang, X Qian, W Li, W Wang, Z Liu - Optics and Lasers in Engineering, 2025 - Elsevier
In this paper, a dual-channel dispersive interferometer using femtosecond laser is
developed with a reference long optical fiber. The width spectrum of the femtosecond laser …
