Low-order wavefront control using a Zernike sensor through Lyot coronagraphs for exoplanet imaging: II. Concurrent operation with stroke minimization
R. Pourcelot, E. H. Por, M. N'Diaye +16
Wavefront sensing and control (WFSC) will play a key role in improving the stability of future large segmented space telescopes while relaxing the thermo-mechanical constraints on…
Low-order wavefront control using a Zernike sensor through Lyot coronagraphs for exoplanet imaging
R. Pourcelot, M. N'Diaye, E. H. Por +19
Combining large segmented space telescopes, coronagraphy and wavefront control methods is a promising solution to produce a dark hole (DH) region in the coronagraphic image of an o…
Wavefront tolerances of space-based segmented telescopes at very high contrast: Experimental validation
Iva Laginja, Jean-François Sauvage, Laurent M. Mugnier +8
Context: The detection and characterization of Earth-like exoplanets (exoEarths) from space requires exquisite wavefront stability at contrast levels of . On segmented te…
Experimental validation of active control of low-order aberrations with a Zernike sensor through a Lyot coronagraph
Raphaël Pourcelot, Mamadou N'Diaye, Emiel H. Por +11
Future large segmented space telescopes and their coronagraphic instruments are expected to provide the resolution and sensitivity to observe Earth-like planets with a 10^10 contra…
