Abstract
Input optical signals propagate toward first optical diffuser, resulting in first-forward-directed optical signals that propagate toward a second optical diffuser, in turn resulting in second forward-directed optical signals. The second forward-directed optical signals collectively form the optical output of an illumination source that appears to emanate from an enlarged extended source and exhibits reduced speckle. The illumination source can include multiple laser sources formed on or attached to the first optical diffuser.
