We propose a compact catadioptric imaging system based on even aspheric elements to solve some major limitations of conventional panoramic structure, such as field of view, blind spot, resolution, illumination, and less structure is introduced. The design includes a catadioptric front unit that is capable of providing a compression image of a panoramic scene and of relaying high-performance aspheric lenses to a decompression image. It is arranged to project two uncompressed images from two channels on a single sensor. Their optical paths do not interfere with each other, and there is no blind-spot image.
