Hardware demonstration of low-order wavefront sensing and control for HWO exoplanet imaging

We describe a NASA Strategic Astrophysics Technology initiative with an optical wavefront control element for the active correction of low-order wavefront errors in a space observatory coronagraph. This element facilitates the separation of active low-order and static high-order wavefront control to be demonstrated in...

Coronagraph design survey

NASA is embarking on an ambitious program to develop the Habitable Worlds Observatory (HWO) flagship to perform transformational astrophysics, as well as directly image ∼25 potentially Earth-like planets and spectroscopically characterize them for signs of life. This mission was recommended by the Astro2020 decadal sur...
