Steroscopy of Continuous Distribution.

摘要

Stereoscopy is applicalbe to the problem of precisely determining the spatial structure of a photographic record. Using photogrammetric methods,numerical data was obtained for a selected stereo pair of photographs of a barium release cloud produced in the 1971 Secede II test series. The resolution limits of these methods are discussed,based on the inherent limitations of the photographic system. Unresolved problems remaining due to the nature of the photographic image -the cloud itself -are mentioned and a possible path toward their solution is outlined. (Author)
