  • High resolved imaging and superresolved imaging technologies are the hot topics in the electronicoptical tracking, optical remote sensing and the aerospace industry.

Super resolved reconstruction technologies and recent evolution

Abstract: High resolved imaging and superresolved imaging technologies are the hot topics in the electronicoptical tracking, optical remote sensing and the aerospace industry. With transforming an optical imaging system into an electronicoptical imaging one, how to improve the geometric resolution of CCD has become an important problem to develop the high resolution electronicoptical imaging system. In this paper, several methods to realize high resolved constructions are introduced based on theoretical analysis and engineering practice. Then, two kinds of image construction technologies, micro scanning and subpixel, are described, and their shortcomings are discussed in detail. Furthermore, to improve the band width by reconstruction without the spectral alias in supperresolution technologies, a new coding technology combining a optical encoding and the subpixel method is proposed. With the method, the bandwidth has been amplified by three times as compared with that of traditional methods. From what has been discussed above, it comes a conclusion that an optical imaging system combined optical, electronicoptical and signal processing technologies will be an important developing trend.
