New Flat Lens Focuses Without Distortion
yahyamf writes "Applied physicists at Harvard have created an ultrathin, flat lens that focuses light without the distortions of conventional lenses. 'Our flat lens opens up a new type of technology,' says principal investigator Federico Capasso. 'We're presenting a new way of making lenses. Instead of creating phase delays as light propagates through the thickness of the material, you can create an instantaneous phase shift right at the surface of the lens. It's extremely exciting.'" And by "ultrathin," they mean it — 60 nanometers thin. The big advantage for this technology, aimed at telecommunications signals, is that "the flat lens eliminates optical aberrations such as the 'fish-eye' effect that results from conventional wide-angle lenses. Astigmatism and coma aberrations also do not occur with the flat lens, so the resulting image or signal is completely accurate and does not require any complex corrective techniques."
Will is make my ass look big?
Yeah, but then you wouldn't want to make them angry... you wouldn't like them when they're angry.
General Relativity: Space-time tells matter where to go; Matter tells space-time what shape to be.
Sometimes you want to focus on the tits and blur everything else...
Either I'm taking you too literally, or you're doing it wrong.
