Capturing 3D Images From a Kilometer Away
7/18/2013

These figures were photographed from 910m away. The images on the left had more time to collect data. Those on the right show noise from a hasty picture. Facial distortions are due to weak reflection from skin.(Source: Heriot-Watt University)

Since this technology does not do well with the human face, it may not be used for surveilance. I'm sure there will be countless other uses for it.

Wow, this could be extended to 10 km in a few years? I'll bet the CIA would like this technology.

Actually, I'd guess they already have it.

The NSA probably developed it. They have incredibly deep pockets.

Also wouldn't be surprised if Naval Special Warfare Group is not out testing the long range version operationally.  A person camoflaged against a brushy background would stand out as a 3D image--happy hunting.

Re: "does not do well with the human face"

One can anamorphically 'paste' a 2d telescopically derived image (face etc.) onto the I.R. derived 3d object as Google Earth does with land features.

You mention GoogleEarth- that's the thought that came to my mind, but in a slightly different way:  I always imagined that all the terrestrial imaging from space was simply the result of high-end optics and a huge MegaPixel array to capture detail from 100 miles high. (I actually don't have a clue how Google gets that resolution; I'm guessing) But this article seems to describe more of a scanning system than an optics system.  Seems like its more like RADAR than Photography.

Hmm if it has mm resolution at a km what's it like from 5m? Does this mean we can spin someone or something on a stool and get an accurate 3D model? Could be great for engineering an conversion of something for 3D printing. I know there are solutions out there with cameras and lasers but I've not seen anything that was as good as a contact system

The picture quality seems blur but then I guess is due to the fact that they don't work well with the human face, I think they ought to make the resolution better because it goes without saying that agencies like the CIA and FBI will adopt the technology. The environmental monitoring part is pretty fascinating since the natural calamities won't find us with our guards down.

Some of our culture's most enduring robots appeared in the 80s. The Aliens series produced another evil android, and we saw light robot fare in the form of Short Circuit. Two of the great robots of all time also showed up: The Terminator and RoboCop.
A soundproofing invention called Acoustiblok recently won a television challenge to silence an air horn with only a fraction of an inch of polymer material.
Robots came into their own in the 1970s. Gone were the low-budget black-and-white B movies. Now robots roamed in full-color feature films with A-list actors.
Major global metropolitan areas are implementing a vast number of technology, energy, transportation, and Internet projects to make the metropolis a friendlier, greener, safer, and more sustainable place to be.
Here’s a look at robots depicted in movies and on TV during the 1950s and 1960s. We tried to collect the classics here, omitting the scores of forgettable B movies such as Santa Claus Conquers the Martians and Dr. Goldfoot and the Bikini Machine. Stay tuned for slideshows of robot stars from later decades.
