Paper Abstract

A novel imaging system with superresolution is introduced in the paper. The system is consisted of a high resolution lens, the dichroic beam-splitter and the four same area- array CCD sensors which the pixel size is b micrometers square. The five prisms are designed to divide the incident light beam into four beams. The four sensors are set up in the four imaging planes of the imaging system and their central coordinates are respectively (0,0), (b/2, 0), (0, b/2) and (b/2, b/2). Four different images would be simultaneously received through the imaging system for any object. Processing specially, a new image which has higher spatial resolution than the original four images would be achieved. The novel imaging system will be suitable for space application because the configuration is stable and rugged. If this new method is used in the design of high resolution remote sensing payloads to perform Earth observation, the focal length of the new remote sensing system could be reduced about 50 percent keeping the same spatial resolution comparing with the traditional imaging system.
