Anyone with a smartphone knows how impossible it is to take pictures in the dark. At best you get a picture that looks like a pile of dark to darker grains of sand. Researchers, however, have come up with a better way. They've been able to take 'ultra sharp images' with little to no light. Basically, it's creating clear 3D photos from what looks like nothing.

What's impressive is that the new 3D picture in the dark method doesn't even require new technology. It's just new math. The new method uses a single particle of light to mathematically stitch every other piece of the photo together. It's nuts. One photon can turn what looks like haze to a much clearer picture.

Scientific American explains:


In the team's setup, low-intensity pulses of visible laser light scan an object of interest. The laser fires a pulse at a given location until a single reflected photon is recorded by a detector; each illuminated location corresponds to a pixel in the final image.

Electrical engineer Ahmed Kirmani of MIT says that the team didn't invent a new laser or new detector, it just used a new imaging algorithm to pull more information from what was already there. The algorithm figures how different parts of the object make sense (in relation to the light) to paint the picture.

It will basically allow us to see without light. Or I guess, with very little light. Which will make things like military intelligence, spying, the study of things sensitive to light and more a whole lot better.
