"Development of advanced post-processing methods for the direct detection of exoplanets with ground-based high-contrast imagers" Join Zoom Meeting https://univ-amu-fr.zoom.us/meeting/84538326148 Thesis Abstract: “Current high-contrast imaging techniques have limitations (i.e., self-subtraction and oversubtraction) at short angular separations (i.e., <0.3"), precisely where most exoplanets are situated. It is thus necessary to develop advanced post-processing techniques to overcome these […]

In the absence […]
Wavefront architecture of the ELT The ELT Wavefront Control manages the 5 mirrors of the telescope in position and shape and delivers at the interface with the instruments a beam quality compatible with diffraction-limited performance after correction by post-focal AO systems. This is obtained if the spectral distribution of aberrations in the temporal and spatial […]
