Abstract

The subpixel imaging system with line-array CCD sensors and with area-array CCD sensors are introduced in the past paper. The system is consisted of a high-resolution lens, a beam splitter and two line-array CCD sensors or four area- array CCD sensor with subpixel displacements in the focal planes. In order to get a high spatial resolution in the pushbroom direction for pushbroom imaging system, the sample spacing between line images is decreased. Processing the original images got through the subpixel imagin system specially, a new image with higher spatial resolution could be constructed. The imaging system will be suitable for space application because the configuration is stable and rugged. The key techniques involved in the subpixel imagin system are the following: (1) the precision measuring technique of the CCD sensors' location and (2) the technique of the new image constructing.
