New Liquid Camera Lens (image) Rensselaer Polytechnic Institute Share Print E-Mail Caption A new technique for creating liquid lenses with water and sound could enable a new generation of low cost, lightweight, energy efficient cameras. This series of time-lapse photos shows how the lens, made up of two droplets of water vibrating at a high speed, changes shape and, in turn, moves in and out of focus. The time between frames is four milliseconds. Credit Rensselaer/Carlos A.
