Abstract
A system for uniform distribution of light is provided. The system comprises: an integrating rod comprising an output end opposite an input end, the integrator rod configured to emit, at the output end an integrated image of light received at the input end, the integrated image having an etendue Eimg and an area Aimg at a given distance from the output end; and, an apparatus comprising an input side located at the given distance, the apparatus configured to: receive, at the input side, the integrated image from the output end of the integrating rod; split the integrated image into a number N of sub-images, each of the sub-images having an area Asub, and an etendue Esub, such that Aimg is about N*Asub, and Eimg is about N*Esub; and, relay the sub-images.
