FLAT PANEL MULTICOLOR DISPLAY BASED ON INTEGRATED OPTIC SCANNER

THE OVERALL OBJECTIVE OF THE PROPOSED EFFORT IS TO DEVELOP A LOW POWER, COMPACT MULTICOLOR, FLAT PANEL DISPLAY. OUR APPROACH IS BASED ON ILLUMINATING A 3-COLOR PHOSPHOR SCREEN WITH AN INFRARED SEMICONDUCTOR LASER DIODE AND SCANNING IT WITH AN INTEGRATED OPTICS BASED LOW POWER LASER SCANNER. APA OPTICS IS DEVELOPING A LASER SCANNER WHICH HAS NO MOVINGPARTS, IS VERY COMPACT, AND HAS THE POTENTIALS OF PROVIDING VERY HIGH SPATIAL RESOLUTION OVER A LARGE DEFLECTION ANGLE. 1.06-MICRON (INFRARED) DIODE-PUMPED LASER, WHEN USED IN CONJUNCTION WITH "UNCONVERSION" PHOSPHORS, EMITS LIGHT IN VISIBLE SPECTRUM. SUCCESSFUL DEVELOPMENT OF OUR CONCEPT WILL RESULT IN A SEMICONDUCTOR BASED MULTICOLOR, FLAT PANEL DISPLAY WITH THE DESIRED SMALL-VOLUMN, LOW-POWER FEATURES FOR SPACE WORKSTATION APPLICATIONS. IN PHASE I OF THE PROPOSED EFFORT, WE WILL ANALYZE THE INTERACTION OF OUR PROPOSED LASER SCANNER WITH THE 3-COLOR PHOSPHOR SCREEN, DERIVE REQUIREMENTS AND SPECIFY CONFIGURATIONS FOR ALL THE COMPONENTS OF OUR DISPLAY. WE WILL ALSO EXPERIMENTALLY CHARACTERIZE THE LASER/PHOSPHOR CHARACTERISTICS. IN PHASE II, WE WILL BUILD A FEASIBILITY DEMO, AND DEMONSTRATE THE CONCEPT.
