Subpixel Imaging of Area-Array CCD Based on Micro-Zooming
The spatial domain imaging model of micro- zooming is established.According to the model,the relationship between observed images and ideal high resolution image is given as a set of large,sparse and inconsistent linear equations.And the high resolution image can be reconstructed by solving the equations.The procedure of micro-zooming is equivalent to change the positions and areas of CCD sensor elements,which are related to the magnification of optical system and the locations of the sensor elements respectively.So micro-zooming can be considered as a special case of the micro-translation imaging,which can realize subpixel imaging by translating the CCD sensor in subpixel level during imaging.Ultimately,the experiment concerned on subpixel imaging of area-array CCD is given.Experiment results show that,by micro-zooming,the resolution of imaging system can be enhanced markedly.
