Advancements in Light Emitting Diode (LED) output have allowed the possibility for producing a TV display tSaLR90Y6
using LEDs as the source. This paper presents the design of an optical projection system that takes an array )e d5~ok
of LED sources and scans them onto the screen of a rear projection TV display. A spinning polygon provides ~Z9Eb| B
the scanning motion.
