英文摘要： High resolution spectral imaging is an urgent requirement to achieve reliable target detection and object identification. Optical encoding superresolution method is proposed to improve resolution of spectral imaging in this research, which has not been proposed before. Compared to the conventional superresolution methods using image processing, this method achieves resolution improvement with optical encoding method, thus avoiding time-consuming computer processing. This research provides a brand-new and effective superresolution approach for spectral imaging. We can expect that this research will have important application in spectral imaging and pushes its development.In this research, principle analysis, model simulation and verification experiment are performed to fully understand the optical encoding method for spectral imaging. Firstly, the resolution of spectral imaging system and its space-bandwidth product are analyzed in multi-degree-of-freedom domain using optical information theory. Space-bandwidth product adaption is analyzed for spectral imaging which acquiring spatial and spectra information simultaneously. Optical encoding in different dimensions to change the space-bandwidth product is studied respectively. Secondly, the simulation is performed to verifying the results of principle analysis. Exp
