Interesting article in EE Timers Europe. http://www.electronics-eetimes.com/news/light-centimetre-level-slam...

Working deeply with CERN (European Centre for Nuclear Research) in 2012, French startup Terabee has taken IR-based time-of-flight (ToF) to centimetre-level, boasting update frequencies up to 1kHz for fast moving robots and drones.

Impressive performance with LEDs!

Will probably use a few now, waiting for phased array lasers.

Here is a link to Chris's original Terabee Blog post and discussion which gives a few more specific details, many of which have been removed from the Terabee site.

Exciting stuff. One thing that's not exactly clear, are the sensors returning single point distances or multiple point, i.e. the start of a depth map? I see that it is their intention to do so in the future, just wondering about today.

I am pretty sure each sensor device is a single point (range finder) type, and primarily meant to be used for object avoidance. I also think their goal is to make it affordable enough that you can use multiple devices instead of complicating the setup with the mechanics needed to make a single device line scanning solution. Multiple devices also means you get much higher refresh rates, which can be essential for moving fast in a limited space.

Yes, I'm waiting for a phone with burst illumination laser radar. It's come down in price from $25Mil to only £100k. At that rate should be ready for mobile phones in 5 years? :-) We will all be ready for it when avail :-) On a serious note, looking forward to good depth mapping (640 x 480) in normal daylight up to 50 meters (well whilst dreaming, why not 300 meters :-)). Not hear yet but there are people trying :-)
