Paper Abstract

Based on the principle of non-imaging optics, the illumination system with the laser diode (LD) array is designed for new laser projection system in this paper. Both illumination system designs of the light pipe and fly's eye lens array are presented using standard optical design software Zemax, including the shaping design of laser source beam, uniform light system design and the relay lens design. Good performances are achieved in the simulation. Energy efficiencies of two designs are ⪆65% and both of beam uniformities are near to 96% in the illumination system.
