Abstract
A method and system for producing a compact uniform illumination beam that does not have a positional blind spot. First, non-collimated light beams that have a positional blind spot are received from a light source. Next, the noncollimated light beams are converted into approximately collimated light beams without the positional blind spot. Then, the collimated light beams are split into a plurality of split beams. These split beams are then overlapped to form a compact and uniform illumination beam.
