Proyecciones geológicas tridimensionales con una sola fuente luminosa
Important advances have taken place in different fields of investigation. It is worthwhile revising once more the interesting subject of tridimensional projection, now under new technological basis. The main purpose is to support those areas as in photogeology where the use of volumetric images are irreplaceable.
The elementary principies of stereoscopy are briefly outlined together with the description of an adjustable mirrordevice capable of:
a) fitted into a photographic camera, providing on the same print or slide a stereoscopic pair; and
b) coupled to a conventional projector, superimpose the considered stereoscopic pair on a screen.
