摘要：

E.W. Hansen and J.W. Goodman have reported recently in this journal (Vol. 24 (1978) p. 268) on optical reconstruction from projections via circular harmonic expansion. Here, the reconstruction problem is derived directly as a deconvolution. Thus the necessary optical processing filter is simply the inverse of the Fourier transform of the convolving point response in the suitably distorted projection image. © 1979.
