The proposed evaluation will determine the efficacy of developing and manufacturing a HIGH DEFINITION PROJECTION SYSTEM using CRTs which have faceplates fabricated via SINGLE CRYSTAL FACEPLATE TECHNOLOGY. Specifically, based on faceplate manufacturing data gathered to date, the feasibility of manufacturing 4 inch or 5 inch faceplates will be established. Concurrently, based on luminance versus beam current data gathered to date, projections of performance for larger size faceplates will be made. Assuming that performance characteristics are not limiting, the optimal size projector for the simulator application industry will be evaluated. Specifically, tradeoffs will be made of weight, performance, number c,f units to fill the standard simulator requirement, effect on subsystem parameters; eg, motion base, cost impact at the system level, and the overall effect of advanced microelectronics technologies; ie, surface mounter hybrid, on projector performance, weight and reliability will be assessed. Intrinsic to the evaluation will be the applicability of T1D80 high performance circuitry to the selected projector implementation.
