We present a first proof-of-concept study of a broadband dual-comb HSL system based on a 1 GHz dual-comb supercontinuum (SC). The SC spans from 820 to 1300\u00a0nm, generated via coherent spectral broadening of a free-running single-cavity dual-comb oscillator at 1053 nm in a single nonlinear photonic crystal fiber. The HSL system achieves a sub-\u00b5m ranging precision on a non-cooperative target at an update rate of 670 Hz. The shot-noise limited electronic dual-comb interferograms furthermore encode the spectral information of the target reflection across the SC bandwidth. This allows the capture of precise 3D point clouds with spectral signatures, unlocking new possibilities for spectrum-based material classification.<\/jats:p>","DOI":"10.1364\/ol.550505","type":"journal-article","created":{"date-parts":[[2025,1,10]],"date-time":"2025-01-10T08:00:42Z","timestamp":1736496042000},"page":"1289","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Broadband hyperspectral LiDAR with a free-running gigahertz dual-comb supercontinuum"],"prefix":"10.1364","volume":"50","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7559-2328","authenticated-orcid":true,"given":"S.
