Correlation between the DOC and the disordered metasurface design. a Diagram of the synthesis of the transmitted function T of the disordered metasurface. b, c Intensity (top) and phase (bottom) distributions on the metasurfaces to manipulate spatial coherence with various prescribed DOC (HG22 in b, LG5 in c). The coherence lengths are 25 μm (left) and 10 μm (right). d An illustration of the spatial coherence manipulation with the metasurface. The spatial correlation of the instantaneous intensity distributions at the source plane determines the DOC of the average intensity transmitted from the metasurface
