Abstract
Apparatus for reducing speckle, including a first coherence-reducing component, having a first array of transparent first elements arranged to receive different, respective first portions of a collimated light beam that is incident on the first component, the first elements generating different, respective optical lengths with respect to the light beam passing therethrough and outputting the respective first portions as respective first collimated sub-beams. The apparatus further includes a second coherence-reducing component, having a second array of transparent second elements arranged to receive different, respective second portions of each of the first collimated sub-beams of the light beam, the second elements generating different, respective optical lengths with respect to the light beam passing therethrough and outputting the respective second portions as respective second collimated sub-beams. The apparatus also includes a light combiner, which is arranged to combine the second collimated sub-beams into a collimated output beam.
