Diversity among other worlds: characterization of exoplanets by direct detection
J. Schneider, A. Boccaletti, A. Aylward +34
The physical characterization of exoplanets will require to take spectra at several orbital positions. For that purpose, a direct imaging capability is necessary. Direct imaging re…
Wavefront error correction and Earth-like planet detection by Self-Coherent Camera in space
R. Galicher, P. Baudoz, G. Rousset
In the context of exoplanet detection, the performance of coronagraphs is limited by wavefront errors. To efficiently correct for these aberrations with a deformable mirror, it is…
Theory and laboratory tests of the multi-stage phase mask coronagraph
P. Baudoz, R. Galicher, J. Baudrand +1
A large number of coronagraphs have been proposed to overcome the ratio that exists between the star and its planet. The planet finder of the Extremely Large Telescope, which is ca…
Expected Performance of a Self-Coherent Camera
R. Galicher, P. Baudoz
Residual wavefront errors in optical elements limit the performance of coronagraphs. To improve their efficiency, different types of devices have been proposed to correct or calibr…
Exoplanet Imaging with a Phase-induced Amplitude Apodization Coronagraph III. Hybrid Approach: Optical Design and Diffraction Analysis
E. A. Pluzhnik, O. Guyon, S. T. Ridgway +4
Properly apodized pupils can deliver point spread functions (PSFs) free of Airy rings, and are suitable for high dynamical range imaging of extrasolar terrestrial planets (ETPs). T…
Exoplanets imaging with a Phase-Induced Amplitude Apodization Coronagraph - I. Principle
Olivier Guyon, Eugene A. Pluzhnik, Raphael Galicher +3
Using 2 aspheric mirrors, it is possible to apodize a telescope beam without losing light or angular resolution: the output beam is produced by ``remapping'' the entrance beam to p…
