RELATIONSHIP BETWEEN THE FOCAL INTERVAL AND THREE-DIMENSIONAL IMAGE IN STEREOGRAPHY (II. Radiographic Technology for Stereoscopic Magnification)

Abstract

In stereography, 5 factors should be considered in the reconstruction of a three-dimensional image. 1. Focal interval of the rediographical system. 2. Pupil-pupil distance of the observer. 3. Focus-film distance of the radiographical system. 4. Film-pupil distance of the viewing system. 5. Film arangement of the stereographical system. We have investigated stereographical image distortion caused by exposure at various focal distances.
