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 new wide-angle lens is lighter, smaller and more affordable than commercially available “rectilinear” lenses, which also produce low-distortion views. The researchers present their new feat of optical technology in the Dec. 1 issue of Applied Optics, a publication of the Optical Society of America.
