Dark Hole Maintenance and A Posteriori Intensity Estimation in the Presence of Speckle Drift in a High-Contrast Space Coronagraph

Dark zone maintenance results for segmented aperture wavefront error drift in a high contrast space coronagraph

“…7 Here, we demonstrate maintenance of the dark zone contrast in the presence of a wavefront error drift at monochromatic levels of 2.5 × 10 −8 (IrisAO drift) and 5.9 × 10 −8 (all DMs drift), as well as 7.0 × 10 −7 at multiple wavelengths (BMC drift). This work is an extension of Redmond et al 2020 8 and Pogorelyuk et al 2019 9 which can be referred to for additional background and results.…”
