Abstract

Speckle fields contain many random dark and bright spots. In traditional speckle interference measurement technique, the information of the bright areas is fully utilized, and the speckle vortices that exit in the dark areas are often overlooked. The generation of speckle vortices by using phase-only liquid crystal spatial light modulator (LC-SLM) combined with the double Archimedes’ spiral micro-holes array is experimentally and theoretically studied. In the experiment, the gray image of double Archimedes’ spiral micro-holes array is displayed on the screen of LC-SLM, and the output optical field is captured by a CCD camera. The numerical simulations and experimental results show that speckle vortices can be generated by using this method.
