Abstract:

	The overall objective of this project is to develop a low-power, compact, multicolor,
flat-panel display. The approach is based on illuminating a three-color phosphor
screen with an infrared semiconductor laser diode and scanning it with an integrated-optics-based,
low-power laser scanner. The firm is developing a laser scanner which has no moving
parts, is very compact, and has the potential to provide very high spatial resolution
over a large deflection angle. A 1.06-micron diode-pumped laser, when used in conjunction
with "unconversion" phosphors, emits light in the visible spectrum. Successful development
of the concept will result in a display with the desired small-volume, low-power
features for space workstation applications. In Phase I, the interaction of the laser
scanner with the three-color phosphor screen will be evaluated. The requirements
and configurations for all the components of the display will be specified and the
laser-phosphor interactions will be characterized. In Phase II, a feasibility demonstration
unit would be built.
