Abstract: | We describe a robust method by which the spatial coherence from all pairs of points along a line may be simultaneously acquired from an image formed by diffraction from a phase discontinuity. In contrast to other methods, this approach can accurately reveal weak correlations in the tails of a coherence function. |
