内容記述 A single-pinhole camera is usually used for X-rey imaging. In URA coded aperture camera, the pinhole is replaced by multi-pinhole arrays arranged in m-sequences. Since the URA camera can view the object with a large solid angle, it can also provide some tomographic resolution for three-dimensional objects. But a reconstructed image is blurred by defocus artifact. In this paper, we propose a new iterative algorithm to remove the defocus artifact. We show that the reconstructed image can be improved by using the proposed iterative algorithm.
