Technique gets clear images from light reflected off blank paper

Totally different concept, but this reminds me of the anecdotes my professor would tell us about the possibility of eavesdropping on a monitor (CRT then) based on the light radiation emitted, and not from seeing the actual image itself

Article describing novel way to produce images, yet no images produced in article.<p>Further investigation finds a few thumbnails an a paywall.

Interesting stuff!<p>There's also an article about it on Petapixel: <a href="http://www.petapixel.com/2012/07/16/researchers-develop-camera-that-uses-natural-light-to-see-around-corners/" rel="nofollow">http://www.petapixel.com/2012/07/16/researchers-develop-came...</a><p>and the full academic paper is available here: <a href="http://arxiv.org/pdf/1202.2078.pdf" rel="nofollow">http://arxiv.org/pdf/1202.2078.pdf</a>

At last! Something that comes close to explaining the "seeing around a corner in a scanned picture" scene in Blade Runner...
