Paper Abstract

Based on analyzing the LC rear projective TV system, a fly-eyes lens array telecentric illumination system has been designed, which can magnificently improve the optical performance. The modeling result by means of the LightTools software shows that the uniformity can reach (+4.8%, -6.0%). And the effective energy can be above 91%. At the same time this paper also explicates the method of coupling of illumination system and projection lens system.
