Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display -8g ;t3z
using LEDs as the source. This paper presents the design of an optical projection system that takes an array ]U]{5AA6
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides &FGz53fd4
the scanning motion.
