This Telescope Shoots Lasers to Unlock the Mysteries of the Cosmos

Ground-based telescopes have long struggled to achieve the image clarity and resolution of their orbiting cousins due in large part to atmospheric distortions. That's why we build observatories on mountain tops: to minimize the amount of atmosphere between the telescope and incoming starlight. But with the help of a… » 7/04/13 11:00am 7/04/13 11:00am

Sound Wave-Driven Liquid Lenses Good For Lightweight Future Phones, UAVs

Scientists at Rensselaer Polytechnic Institute have come up with this freaky adaptive liquid-lens that can capture 250 in-focus images per second. It's essentially droplets of water in a pair, trapped in chamber and driven by a high-frequency sound wave to oscillate.As the drops wiggle back and forth, surface tension… » 9/23/08 6:12am 9/23/08 6:12am
