 note = {Penumbral imaging is a powerful imaging technique for radiations with long mean-free path. Since the reconstruction is based on deconvolution, the technique is sensitive to noise contained in penumbral images. Uniformly redundant penumbral array (URPA) technique can improve the SN ratio of penumbral images. In URPA, the penumbral apertures are arranged in m-sequence. In the reconstruction process from the coded data, penumbral image is obtained by correlation to decoding operator. The reconstructed image can be obtained by use of the Wiener filter. In this article, the three-dimensional reconstruction of the URPA and its tomographic resolution are stated., 論文},
