Researchers at the University of Illinois at Urbana-Champaign (Urbana, IL) and Northwestern University (Evanston, IL) have succeeded in developing the first curvilinear or hemispherically shaped working camera that reduces optical distortions associated with flat-sensor cameras. The camera is built from planar silicon optoelectronic components that are formed into an eye-shape nonplanar distributed focal array using a unique and repeatable process. The camera follows the development of expandable silicon designed to meet large-area applications and a curved silicon sensor array, both at Stanford University, which was reported in the March and June 2008 issues of Laser Focus World (see www.laserfocusworld.com/articles/322010 and www.laser-focusworld.com/articles/330736).
