Patent ID: 8835804

Claim:
A system for homogenizing the optical intensity profile of light, comprising: a plurality of fiber coupled light sources, for emitting fiber output beams from corresponding fiber output ends thereof, said fiber output ends including a first set of said fiber output ends displaced from each other and arranged to emit a corresponding first set of said fiber output beams in a first direction and a second set of said fiber output ends displaced from each other and arranged to emit a corresponding second set of said fiber output beams in a second direction, each of said fiber output beams having a principal ray; a light pipe optically coupled to said fiber output beams for producing a light pipe output beam; an interleaver configured to intersect said first and second sets of fiber output beams and direct said principal rays thereof into a common direction in relation to an optical axis; and one or more optical elements situated along said optical axis between said interleaver and said light pipe, said one or more optical elements including a telecentric lens for telecentrically imaging said fiber output beams into said light pipe.
