ABSTRACT Y^ 2]*e%
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display 8i~n;AhDs
using LEDs as the source. This paper presents the design of an optical projection system that takes an array w%?6s 3
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides dV7~C@k6k8
the scanning motion.
