Re Quanergy: Although the Quanergy site claims all their units have no moving parts, a university in France which evaluated their M8, the only thing they're actually shipping, writes this: The Quanergy M8 LIDAR system consists of 8 2D line scanners located on a spinning head which can spin at a rate from 5 Hz to 30 Hz. The 8 lasers are spread out over a 20° vertical field of view (FOV) and the entire unit rotates to give a full 360° by 20° FOV.[1]

There are lots of companies working on low-end LIDAR. ASC's technology is known to work well; it just costs too much because it involves custom sensor ICs built with a nonstandard GaInAs process. Quanergy has been issuing a lot of press releases and getting funding, but they seem to have backed off from their < $100 solid-state sensor and are now selling $7500 rotating machinery like Velodyne's spinning top. There are also some companies touting continuous-wave systems, which usually don't work in sunlight or have much range, but are useful for indoor robots.
Fraunhofer is working on a technology for making flash LIDAR sensors using a regular CMOS process.[1] If that works, these things will come down to digital camera prices in volume.
Bloomberg has most acquisition information. I picked this up because I've been following ASC since the 2005 DARPA Grand Challenge days, when I went to Santa Barbara to see their technology. It was just on an optical bench then, not ready to deploy, but they had the technology with long-term promise. I dragged a VC down there to talk to them, but he didn't see near-term volume application. He was right; only now is there a market in sight for LIDAR units by the millions. High production volume is probably still 5-10 years away.
