Focal plane modal estimation of high-order wavefront drifts on coronagraphic testbeds
The upcoming Habitable Worlds Observatory requires precise wavefront stability over long observation periods to directly image Exo-Earths of interest, which are 10 orders of magnitude dimmer than their host star. Dark zone maintenance (DZM) has been proposed as a focal plane high-order wavefront sensing and control (HO...
