“…While the phase of a segmented wavefront has been measured directly [24], a more popular technique is based on the Shack-Hartmann gradient sensor [25,26], originally developed to test lenses. The incoming wavefront is segmented by an array of positive lenslets which produces an array of spots at their focal plane.…”

In this work we construct examples of paraxial light fields whose intensities defined at all points in space do not have a corresponding cross-spectrally pure field amplitude reproducing the same set of transported intensities at all transverse planes. Nevertheless, two spatially separated transverse plane intensities as drawn from these examples are shown to have a corresponding cross-spectrally pure field amplitude, which, through paraxial free propagation between these two planes, reproduces the drawn transverse plane intensities. And the phase associated with such a field amplitude at a given transverse plane is found to be contextual, and intrinsically dependent on the pairing plane.
