摘要

A novel superresolution imaging system with line-array CCD sensor is introduced in the paper. The system is consisted of a high resolution lens, the beam splitter and two line- array CCD sensors. The two same line-array CCD sensor which the pixel size is b $mu@m by b $mu@m are set up in the two imaging planes of the imaging systems and their central coordinates are respectively (0,0) and (b/2, 0). In order to get the high spatial resolution along the pushbroom direction, the sample spacing between line images is decreased. The line array is moved only half a pixel width instead of a full pixel width for each line image scan. Two different images would be simultaneously got through the novel linear pushbroom imaging system for the moving scenes. Processing specially, a new image with higher spatial resolution than the original two images would be obtained. The novel imaging system will be suitable for space application because the configuration is stable and rugged. If the new method is used in the design of 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. If the sensor is area-array CCD in the imaging system, the superresolution imaging system would be consisted of a high resolution lens, the beam splitter and four area-array CCD sensors with subpixel displacements in the focal planes.
