Precise and fast determination of position and orientation, which is normally achieved by
distance and angle measurements, has broad applications in academia and industry. We …

Soliton rain is a bunch of small soliton pulses slowly drifting near the main pulse having the
period of a round trip. For Er-doped fiber laser mode-locked by carbon nanotubes, for the …

Dual-comb LiDARs have the potential to perform high-resolution ranging at high speed.
Here, through an implementation involving electro-optic modulators and heterodyne …

Dual-comb spectroscopy has been an infusive spectroscopic tool for gas detection due to its
high resolution, high sensitivity, and fast acquisition speed over a broad spectral range …

Noise in mode-locked lasers has been a central issue for dual-comb metrological
applications. In this work, we investigate the laser intensity noise on dual-comb absolute …

A dual-comb ranging (DCR) system without spectral aliasing based on free-running fiber
lasers was proposed. By monitoring the repetition frequency over time, we compensate for …

We present a continuous dynamic frequency scanning interferometry (DFSI) measurement
method based on motion phase synchronization compensation and calibration. By …

By using fully-locked Ti: sapphire combs operating with repetition-frequencies of 513 MHz,
we demonstrate high-speed dual-comb distance metrology with update rates up to 130 kHz …
