Optical Lens :: New wide-angle lens produces pictures without distortion
South Korean researchers have designed and built an inexpensive optical lens that collects light from a large area and produces a virtually distortion-free wide-angle image. Standing in contrast to commonly known “fisheye” lenses, which produce significant amounts of visual distortion, low-distortion wide-angle lenses can potentially improve image-based applications such as security-camera systems and robot navigation. The research appears in the December 1 issue of Applied Optics, a publication of the Optical Society of America.
