Absolute distance measurement is a fundamental technique in mobile and large-scale
dimensional metrology. Dual-comb ranging is emerging as a powerful tool that exploits …

We present a progress review on the advance of distance measurements made at KAIST by
making use of mode-locked lasers as the light source to meet ever-growing industrial …

We demonstrate dual-comb time-of-flight absolute distance measurement with a free-
running dual-wavelength dual-comb mode-locked Er-fiber laser. An anodized aluminum …

Frequency-modulated continuous-wave LIDAR (FMCW LIDAR) has been widely used for
both scientific and industrial tools. Here, in this report, a new class of LIDAR technique …

The spectral domain interferometer (SDI) has been widely used in dimensional metrology.
Depending on the nature of the SDI, both wider spectral bandwidth and narrower linewidth …

Kerr frequency combs have been attracting significant interest due to their rich physics and
broad applications in metrology, microwave photonics, and telecommunications. In this …

We present an absolute distance measurement system using a phase-stable dual-comb
system with 56.09 MHz repetition rate and 2 kHz repetition rate difference. A relative phase …

We experimentally demonstrate a method for absolute distance measurement using a triple-
comb-based multi-heterodyne interferometer which has the capacity to simultaneously …

The interferometric signals produced in conventional dual-comb laser ranging require
femtosecond lasers with long-term carrier-envelope offset frequency stability, and are limited …

Pulse trains emitted from dual-comb systems are designed to have low relative timing jitter,
making them useful for many optical measurement techniques such as optical ranging and …
