72.3: A Direct-View Laser-Phosphor Display with a High-Reflection Wide-Angle-Scanner

A bright direct view laser phosphor display with a large scanning angle has been developed. A scan mirror, to which a dielectric multilayer was applied on a glass substrate, achieved over 99% reflectivity and withstands large laser power. An optical scanning angle of over +/- 21.5 degrees was verified, which was achieved with our dual moving-magnet drive design. Expansion optics for expanding the scanning angle by 1.5 times were developed. The effectiveness of the proposed devices was verified by projecting images on the display.
