Abstract
For the shortcomings of methods used to improve the image spatial resolution of current linear charge coupled device (CCD) FPD System, a new sampling method is proposed, and a high-resolution FPD System is designed. Two same linear CCD cameras arc fixed with specific spatial arrangement, namely both camera 1 and camera 2's CCD scan the object with a tilt angle B, and image correction and pixel interpolation arc also used for getting high-resolution image. The experimental results show that, compared with the regular scanning mode equipped with a signal camera and =0¡ã, in our method cameras with slant angle =60¡ãenables the image spatial resolution doubled, and keeps the field of view unchanging. It is easy to realize the designed system in engineering, very economical and convenient to maintain it, and only using the existing imaging device to obtain higher-resolution images.
