Experimental validation of active control of low-order aberrations with a Zernike sensor through a Lyot coronagraph

Pourcelot, Raphaël N'Diaye, Mamadou Por, Emiel

Future large segmented space telescopes and their coronagraphic instruments are expected to provide the resolution and sensitivity to observe Earth-like planets with a 1010 contrast ratio at less than 100 mas from their host star. Advanced coronagraphs and wavefront control methods will enable the generation of high-contrast dark holes in the...

James Webb Space Telescope optical simulation testbed V: wide-field phase retrieval assessment

Laginja, Iva Brady, Gregory Soummer, Rémi

The James Webb Space Telescope (JWST) Optical Simulation Testbed (JOST) is a hardware simulator for wavefront sensing and control designed to produce JWST-like images. A model of the JWST three mirror anastigmat is realized with three lenses in the form of a Cooke triplet, which provides JWST-like optical quality over a field equivalent to a...
