Conventional video cameras have limited fields of view which make them restrictive in a variety of applications. A catadioptric sensor uses a combination of lenses and mirrors placed in a carefully arranged configuration to capture a much wider field of view. At Columbia University, we have developed a wide range of catadioptric sensors. Some of these sensors have been designed to produce unusually large fields of view. Others have been constructed for the purpose of depth computation. All our sensors perform in real time using just a PC.
