We consider the problem of reconstructing remotely obtained images from image-plane detector arrays. Although the individual detectors may be larger than the blur spot of the imaging optics, high-resolution reconstructions can be obtained by scanning or rotating the image with respect to the detector. As an alternative to matrix inversion or least-squares estimation [Appl. Opt. 26, 3615 (1987)], the method of convex projections is proposed. We show that readily obtained prior knowledge can be used to obtain good-quality imagery with reduced data. The effect of noise on the reconstruction process is considered.
我们考虑从图像平面探测器阵列重建远程获取图像的问题。尽管单个探测器可能大于成像光学系统的模糊斑，但通过相对于探测器扫描或旋转图像，可以获得高分辨率重建。作为矩阵求逆或最小二乘估计[《应用光学》26, 3615 (1987)]的替代方法，我们提出了凸投影方法。我们表明，容易获得的先验知识可用于以减少的数据量获得高质量图像。同时考虑了噪声对重建过程的影响。
