Astech proposes computer software for a tachistoscope, consisting of a Genisco GCT-3000 display and a PDP-11/34a processor, for research in visual psychophysics and physiology. In addition to controlling and administering tests, the software will feature innovative support for developing graphic displays of images of a rigorously defined spatial scene, where: (1) images are formed on a CRT defined as the aperture and focal surface of an independent mobile observer optical system. (2) the scene is illuminated by multiple mobile light sources capable of diverse chromatic attributes and radiant geometries. (3) objects reflect colors defined by Cie Chromaticity co-ordinates and move according to rigorous application of physical laws. Phase I work will consist of functional requirements definition, general design and feasibility demonstration.
