Probing Photon Statistics in Adaptive Optics Images with SCExAO/MEC

Steiger, Sarah Brandt, Timothy D. Guyon, Olivier

We present an experimental study of photon statistics for high-contrast imaging with the Microwave Kinetic Inductance Detector (MKID) Exoplanet Camera (MEC) located behind the Subaru Coronagraphic Extreme Adaptive Optics System at the Subaru Telescope. We show that MEC measures the expected distributions for both on-axis companion intensity and...

Mid-order wavefront control for exoplanet imaging: preliminary characterization of the segmented deformable mirror and Zernike wavefront sensor on HiCAT

Buralli, Benjamin N'Diaye, Mamadou Pourcelot, Raphaël

We study a mid-order wavefront sensor (MOWFS) to address fine cophasing errors in exoplanet imaging with future large segmented aperture space telescopes. Observing Earth analogs around Sun-like stars requires contrasts down to 10^-10 in visible light. One promising solution consists of producing a high-contrast dark zone in the image of an...
