Abstract
We develop a simple, robust method of customizing the intensity statistics of laser speckles and introducing non-local correlations among the speckle grains. The tailored speckle patterns exhibit radically different topologies and varying degrees of spatial order. The various families of speckles are created by encoding high-order correlations into the phase front of a monochromatic laser beam with a spatial light modulator. Recently, we generate volumetric speckles with distinct tailored intensity statistics on multiple designated planes. The ability to design 3D speckle statistics opens many possibilities: three-dimensional imaging and sensing, optical trapping and manipulation.
