Using a silicon chip coated in nanoantennas, they effectively made a metamaterial mirror for a laser, allowing a 1D laser scanner LIDAR that is solid state. Made using methods similar to LCD manufacturing, which means the beam can be actively scanned at will, so not a fixed scanning cycle either.

Interesting that they have to spread out the beam first before hitting the dump, and the dump is made from a block of graphite. The quench protection via electrical dump to resistor grids is also interesting. I would have thought they might try to recover the power from the dump into some other storage, but I guess the safety criticality means they don't.

AtomVM: how to run Elixir code on a 3 $ microcontroller
AtomVM is a tiny portable virtual machine that allows BEAM code to run on microcontrollers with less than 500KB of RAM such as the ESP32. So what does it mean? In few words you can flash AtomVM on an…
