Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display vL^ +X`.td
using LEDs as the source. This paper presents the design of an optical projection system that takes an array !-

of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides !;hp
the scanning motion.
