计算了X射线针孔成像系统的点扩散函数矩阵,利用Lucy-Richardson算法对模拟和真实的针孔图像进行了较好的恢复,分析了恢复后得到的结果,给出了合理的迭代次数、恢复方法细节和恢复图像的分辨率,并用模拟实验验证了Lucy-Richardson算法对针孔图像进行恢复的可靠性.
The matrix of the point spread function for an X-ray pinhole camera system has been calculated. The computer-simulated pinhole images and real pinhole images measured in laser-plasma experiments have been restored using Lucy-Richardson algorithm. The number of iterations the resolution of the restored imaging and the details of the restore method have been discussed. The reliability of the restoration algorithm is also verified by a simulated optical experiment.
