Development of High Performance Displays for Mammography

This research program is directed toward the development of markedly improved high performance displays, designed to enhance diagnosis in digital mammography. The activities of the first year centered around the development of instrumentation for the experimental investigation of the novel cathodoluminescent materials and substrates with respect to their potential for use in electronic displays. 1 A demountable display tube was designed, ordered and constructed. It permits investigation of samples of the novel cathodoluminescent materials and their respective substrates with respect to characteristic display performance measures. 2 A probe was constructed which permits measurement of luminance and contrast of luminescent samples in the presence of glare 3 A compact display evaluation system was developed which permits measurement of pertinent display characteristics 4 A contract was established with the University of California at Berkeley to deposit Cs on substrates provided by the U of Arizona for investigation in the demountable display tube.
