Experimental validation of joint phase and amplitude wave-front sensing with coronagraphic phase diversity for high-contrast imaging
Olivier Herscovici-Schiller, Laurent M. Mugnier, Pierre Baudoz +3
Context. The next generation of space-borne instruments dedicated to the direct detection of exoplanets requires unprecedented levels of wavefront control precision. Coronagraphic…
Compensation of high-order quasi-static aberrations on SPHERE with the coronagraphic phase diversity (COFFEE)
B. Paul, J. -F. Sauvage, L. M. Mugnier +6
The second-generation instrument SPHERE, dedicated to high-contrast imaging, will soon be in operation on the European Very Large Telescope. Such an instrument relies on an extreme…
High-order myopic coronagraphic phase diversity (COFFEE) for wave-front control in high-contrast imaging systems
B. Paul, L. M. Mugnier, J. -F. Sauvage +1
The estimation and compensation of quasi-static aberrations is mandatory to reach the ultimate performance of high-contrast imaging systems. COFFEE is a focal plane wave-front sens…
Calibration of quasi-static aberrations in exoplanet direct-imaging instruments with a Zernike phase-mask sensor
M. N'Diaye, K. Dohlen, T. Fusco +1
Context. Several exoplanet direct imaging instruments will soon be in operation. They use an extreme adaptive optics (XAO) system to correct the atmospheric turbulence and provide…
Coronagraphic phase diversity: performance study and laboratory demonstration
B. Paul, L. M. Mugnier, J. -F. Sauvage
The final performance of current and future instruments dedicated to exoplanet detection and characterization (such as SPHERE on the European Very Large Telescope, GPI on Gemini No…
