Paper Abstract

Partially coherent beam is generated by imposing dynamic random phase to completely coherent beam. The coherence of partially coherent beam can be controlled by the randomness of random phase. The speckle pattern of the partially coherent beam passing through scattering medium is studied. The speckle pattern can be modulated into a bright focal spot by wavefront shaping. The influence of the coherence on the focusing is investigated.
