Does anyone know of any examples of a "solid state" lidar as mentioned in the article? Im unable to visualise how such a thing would actually work, and its got me excited!

Maybe they use a digital micromirror device also used in dlp projectors. By using a fish eye lens you could use the mirror array to look around and calculate the traveling distance of light pulses. I am also thinking about a 3d camera. Maybe those are getting good enought to measure distance.

  I thought the micro-mirror approach would be considered electromechanical and not solid-state?

  Another possibility might be to use multiple solid state laser transmitter/receiver pairs located close together, kind of like ink-jet printer nozzles. Because they're discreet, you would lose some resolution compared to a continuous scan system, but it might be OK for the purpose of staying in a road. And, since the vehicle is moving (most of the time) anyway, maybe multiple returns can be integrated something like a synthetic aperture radar system to form a more complete picture.

Time-of-Flight cameras are one option: https://en.wikipedia.org/wiki/Time-of-flight_camera https://en.wikipedia.org/wiki/Time-of-flight_camera

  From their site Based on the ToF principle, the cameras employ an integrated light source. The emitted light is reflected by objects in the scene and travels back to the camera, where the precise time of arrival is measured independently by each pixel of the image sensor, producing a per-pixel distance measurement.

  Is there something like this available, but in the <$250 segment. These I understand are > $1000 market.

      Lidar competes for outdoors scanning. Isnt kinect out of that game?

TriLumina (http://trilumina.com/ http://trilumina.com/) was at Connected Car Expo this year. They didn't have an actual device to show, but they have developed a solid state LIDAR with some pictures and a data sheet on their website.
