    摘要: A system and method are used to form incoherent beams from at least a partially coherent beam, such that interference or speckle patterns are substantially eliminated. A rotating optical element directs the partially coherent beam to reflect from an angular distribution changing element to form an incoherent beam. The partially coherent beam can be directed at valying angles or positions onto the angular distribution changing element through rotation of the rotating optical element. The angles can vary as a function of time.
