researchers have created a new lens they say could revolutionize photography by allowing the smallest cameras to take crystal-clear zoom photos. The new lens, five times thinner than a sheet of paper, can zoom and focus with no moving parts, potentially eliminating the distortion caused by digital zoom and the bulky glass of conventional optical lens. Galstian's lens adds a light-sensitive compound to a thin sheet of liquid crystals, eliminating the need for the finely ground glass of conventional photographic equipment.
When the sheet is zapped with a laser beam, the center becomes denser than the edges of the lens. Small jolts of electricity change the material in the lens to bend light and adjust focus and zoom.
