This invention is a reference-free snapshot wavefront camera that can be used to measure both amplitude and phase of the wavefront. The camera uses a two-dimensional diffraction grating to split the incoming wavefront into multiple copies which then travel through a lens that focuses them onto a sensor in a camera array. The resulting wavefront information...
