This is the highest-resolution image that could ever be made.
What resolution is Retina resolution? 220 ppi (like the new MacBook Pro)? 264 ppi (like the iPad 3)? Or the amazing 326 ppi found on the iPhone?
What about 10,000 ppi? That’s the resolution of an image printed by researchers at the Agency for Science, Technology and Research in Singapore. It’s the picture you see above which, at just 50 x 50 microns, is the same size as a single pixel on an Apple Retina display.
Imagine that you could just point your iPhone’s camera at your baby and it would immediately tell you his vital signs: heartbeat and so on. Or that you could fire up an app and it could pick out tiny, invisible movements from what looks like a still video. Using a process called Eulerian Video Magnification, boffins at MIT are doing this already.
