Abstract

The reconstruction of a two-dimensional sectional image from one-dimensional projections can be achieved in parallel by a deconvolution, if the projections are arranged in properly chosen coordinates. In most cases the deconvolution result is still to be coordinate-transformed. The reconstruction theory is briefly discussed and illustrated by digital computer simulations. A coherent optical realization of the deconvolution is described and results are shown. Problems due to spatial truncation are discussed.
