Freezing the speckles: focal plane wavefront sensing with the spatially clipped self-coherent camera
The next generation of Extremely Large Telescopes (ELTs) and the Habitable Worlds Observatory (HWO) require active speckle suppression to directly image exo-Earths. Focal plane wavefront sensing and control allows us to detect and remove time-varying speckles through measurements of the electric field, ideally with a s...
