ABSTRACT:
A super wide-angle imaging system has a short total track length. The lens system is a retrofocus type lens system that uses only a few lenses with no cemented lens elements. Acceptable performance is achieved by taking advantage of subsequent digital image processing. The compact lens system is designed to create optical images that can be restored by subsequent digital processing that compensates for otherwise unacceptable aberrations introduced by the lens system.
