Vibrating Water Creates Miniature In-Focus Images

It’s like seeing the world in a drop of water; actually through a drop of water.
Professor Amir H. Hirsa at Rensselaer Polytechnic Institute has developed a miniature camera that can capture 250 pictures per second while using less energy than other technologies.
According to Hirsa, “The lens is easy to manipulate, with very little energy, and it’s almost always in focus--no matter how close or far away it is from an object.”
The lens is made up of two drops of water that are constrained in a small tube. They are exposed to sound waves so they begin oscillating. The change in geometry forms a constantly shape changing lens. An imaging sensor behind the droplets captures the images and a computer analyzes them, discarding any that are out of focus. The result is a camera that is focused on whatever it sees.
Look for this technology anywhere a small, lightweight, energy efficient camera is needed.
