The interpretation of optical projections
Michael Berry, D F Gibbs · Proceedings of the Royal Society of London A Mathematical and Physical Sciences · 1970
Abstract The first question considered is whether a series of projections (such as X-ray shadowgraphs) of a three-dimensional object can be Used to infer unambiguously the structure of the object, it is shown that this is the case. Secondly, the relations between the statistics of a statistically isotropic object and the statistics of its projection are considered.
