Experimental synthesis of partially coherent beam with controllable twist phase and measuring its orbital angular momentum
Twist phase is a nontrivial second-order phase that only exists in a partially coherent beam. Such twist phase endows the partially coherent beam with orbital angular momentum (OAM) and has unique applications such as in super-resolution imaging. However, the manipulation and the detection of the tw...
