asteroza + lidar   29

They acquired Blackmore, who were mainly developing LIDAR using photonic integrated circuits with frequency modulated continuous wave ranging capability with integrated velocity measurement as well, so you can tell a far object is also a fast mover (like an oncoming car). FMCW is also low power, so it doesn't burn out PIC's like normal high power short burst LIDAR.

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.

Ball Aerospace - OAWL- wind LIDAR
New compact wind LIDAR with long range, which in theory would allow a high altitude balloon to detect favorable wind directions and change altitude to maneuver, becoming effectively stationary.

Beating LIDAR - Achuta Kadambi - MIT Media Lab
Using heterodyning LIDAR to achieve very high resolution at range, and might be able to punch through fog. WHich makes you wonder if the same trick could be used for lasercomm lasers which always had a rain/fog fade problem...

Fully Integrated Hybrid Silicon Two Dimensional Beam Scanner | Bowers
The underlying tech behind Strobe Inc.'s (now GM/Cruise) fancy pants chip LIDAR. Uses optical phased array for one dimensional scanning, and frequency variation through a prism lens to achieve scanning in the other dimension, rather than a full 2D optical phased array (so easier to make?)

Some sort of fancy pants LIDAR that uses continuous light rather than pulses to gather both range and speed info simultaneously. Time of flight plus other tricks?
