DOI: 10.1038/s41467-025-58018-8

Abstract: AI-empowered autonomous vehicles must sense the fast-changing three-dimensional environments with high speed and precision. However, the tradeoff between acquisition rate and non-ambiguity range prevents most LiDARs from achieving high-speed absolute distance measurement. Here we demonstrate… read more here.
