Seeing in the dark... no place is safe from eyes!

Thanks Cabe, for such an informative post . I read somewhere that 3d images in the dark produces results of a quality that a conventional imaging system would require 900 times the light to creat it .

Toolman, the military uses a number of different technologies, and some of them seem to be that old. Those systems that served well seem to stick around for a long time, not at all like consumer stuff.  Newer systems are faster and cheaper and use less battery power, and all of them continue to be really amazing. My criticism is that they cost to much for me to have one as a personal toy. And they are probably not legal for game hunting in the dark, although they would make hunting a lot safer, since one could see the target quite clearly.

  Thank you for the clarification. I should have picked up on that because of the multiple images. Continuing on with your military comment, is that at all like the Starlight Scopes we had in the Viet Nam era? As I recall they magnified available light by a factor of 25,000. but that was a long time ago and my memory may be way off.

High resolution in near darkness is not quite real time, there is a trade off made in collecting those photons and avaeraging them into a picture. Military sniperscope gunsights are a good example of what is quite fast, which is all I can say. But they are certainly not portrait quality images. The accurate statement is "adequate for the application".

The fact that the example here provides four images should tell that the system is not close to real time.

  That is incredible technology and the uses for both military and law enforcement could be staggering. I did not see a time lag mentioned in the article so I am assuming the images occur in real time. The surveillance uses, particularly if coupled with a drone, are spooky. Even if the images are not as good as the final one pictured with the article, the data gathered is impressive.

If the upper left picture represents the raw data collected from the scanner and the lower left picture represents the final resullt after algorithm filtering, this is indeed a very impressive system.  Nice work!

Wow, this is an impressive step forward. Thanks for reporting on this, Cabe. DN previously reported on the femtosecond camera you mention: http://www.designnews.com/author.asp?section_id=1392&doc_id=241180

When you think of the DARPA Robotics Challenge, you may imagine complex humanoid contraptions made of metal and wires that move like a Terminator Series T-90. But what actually happened at the much-vaunted event was something just a bit different.
The machine is claimed to be the largest and most powerful electric pipe-bender on the market, exerting nearly 500,000 lb-ft of torque.
Traditional dev kits are based on a manufacturer’s microcontroller, radio module, or sensor device. The idea is to aid the design engineer in developing his or her own IoT prototype as quickly as possible. A not-so-traditional IoT development kit released by Bosch aims to simplify IoT prototyping even further.
This consulting firm has put together a report detailing the growing biomimicry design field in the US and around the world, from naturally bacteria-repelling surfaces to keratin-inspired polymers.
