Implicit Electric Field Conjugation Through a Single-mode Fiber

Joshua Liberman, Jorge Llop-Sayson, Arielle Bertrou-Cantou +4

Connecting a coronagraph instrument to a spectrograph via a single-mode optical fiber is a promising technique for characterizing the atmospheres of exoplanets with ground and spac…

Benefits of adding radial phase dimples on scalar coronagraph phase masks

Niyati Desai, Dimitri Mawet, Eugene Serabyn +4

Current scalar coronagraph focal plane mask designs are performance-limited by chromaticity. We investigate the effects of adding central Roddier and dual zone phase dimples to sca…

Topological Designs for Scalar Vortex Coronagraphs

Niyati Desai, Jorge Llop-Sayson, Arielle Bertrou-Cantou +4

The detection and characterization of Earth-like exoplanets around Sun-like stars for future flagship missions requires coronagraphs to achieve contrasts on the order of 1e-10 at c…

Redundant Apodized Pupils (RAP) for high-contrast imagers robust to segmentation-due aberrations and island effects

Lucie Leboulleux, Alexis Carlotti, Mamadou N'Diaye +6

The imaging and characterization of a larger range of exoplanets, down to young Jupiters and exo-Earths will require accessing very high contrasts at small angular separations with…

High contrast imaging wavefront sensor referencing from coronagraphic images

Nour Skaf, Olivier Guyon, Anthony Boccaletti +11

A key challenge of high contrast imaging (HCI) is to differentiate a speckle from an exoplanet signal. The sources of speckles are a combination of atmospheric residuals and aberra…
