  Ever growing pixel acquisition rates in the fields of augmented reality,
autonomous driving and robotics have increased interest in solid state beam
scanning without moving parts. Modern photonic integrated laser ranging
advances towards passive beam steering solutions. Recently demonstrated imagers
based on focal plane arrays, nanophotonic metasurfaces, and optical phased
arrays enable unprecedented pixel resolution and measurement speed. However,
parallelization of >100 lasers and detectors - successfully implemented in
commercial time-of-flight sensors - has not been widely adopted for passive
scanning approaches. Here, we show both inertia-free and parallel light
detection and ranging (LiDAR) with microresonator frequency combs. We used 40
independent channels of a continuously scanned microresonator frequency comb
operated in the chaotic regime in combination with optical dispersive elements
to perform random modulation LiDAR with 2D passive beam steering.
