Freezing the speckles: focal plane wavefront sensing with the spatially-clipped self-coherent camera
A spatially-clipped self-coherent camera variant senses wavefront errors from one image and, combined with implicit electric field conjugation, reduces speckle intensity about twofold in part of a lab dark hole.
