Design, analysis and test of a microdots apodizer for the Apodized Pupil Lyot Coronagraph
P. Martinez, C. Dorrer, E. Aller Carpentier +4
Coronagraphic techniques are required to detect exoplanets with future Extremely Large Telescopes. One concept, the Apodized Pupil Lyot Coronagraph (APLC), is combining an apodizer…
Comparison of coronagraphs for high contrast imaging in the context of Extremely Large Telescopes
P. Martinez, A. Boccaletti, M. Kasper +4
We compare coronagraph concepts and investigate their behavior and suitability for planet finder projects with Extremely Large Telescopes (ELTs, 30-42 meters class telescopes). For…
Adaptive Optics Correction of the Wavefront Distortions Induced by Segments Misalignment in Extremely Large Telescope
Natalia Yaitskova, Christophe Verinaud
The capability of the adaptive optics to correct for the segmentation error is analyzed in terms of the residual wavefront RMS and the power spectral density of the phase. The anal…
Double stage Lyot coronagraph with the apodized reticulated stop for extremely large telescope
Natalia Yaitskova
One of the science drivers for the extremely large telescope (ELT) is imaging and spectroscopy of exo-solar planets located as close as 20mas to their parent star. The application…
Lyot Coronagraphy on Giant Segmented-Mirror Telescopes
Anand Sivaramakrishnan, Natalia Yaitskova
We present a study of Lyot style (i.e., classical, band-limited, and Gaussian occulter) coronagraphy on extremely large, highly-segmented telescopes. We show that while increased t…
