| 摘 要： | 提出了一种提高CCD成像分辨力的反演解析法。通过在一个方向上多次移动CCD获得多幅 低分辨力的图像,合成一幅分辨力提高大于2倍的图像,达到CCD分辨力提高多倍的目的。克服了原有方法最多只能使分辨力提高2倍的缺点。仿真例子证明了其正确性。

| Abstract: | An inversion analysis method for improvement of CCD imaging resolution is proposed. Multi-frame images with low resolution are obtained by moving CCD for many times in a direction and an image that its resolution improved for 2 times is synthesized, thus the objective at improvement of CCD resolution for a many times is attained. The fault that the original method can only improve resolution for 2 times at most is overcome. The simulation examples have demonstrated its correctness. |
