ABSTRACT \tI%[g1M
Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display K4!-%d$
using LEDs as the source. This paper presents the design of an optical projection system that takes an array U8Y%rFh1
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides yQ[;y~W
the scanning motion.
