Optimizing the subwavelength grating of L-band Annular Groove Phase Masks for high coronagraphic performance
Ernesto Vargas Catalan, Elsa Huby, Pontus Forsberg +9
Context. The Annular Groove Phase Mask (AGPM) is one possible implementation of the vector vortex coronagraph, where the helical phase ramp is produced by a concentric subwavelengt…
The QACITS pointing sensor: from theory to on-sky operation on Keck/NIRC2
Elsa Huby, Olivier Absil, Dimitri Mawet +5
Small inner working angle coronagraphs are essential to benefit from the full potential of large and future extremely large ground-based telescopes, especially in the context of th…
MICADO: first light imager for the E-ELT
R. Davies, J. Schubert, M. Hartl +80
MICADO will equip the E-ELT with a first light capability for diffraction limited imaging at near-infrared wavelengths. The instrument's observing modes focus on various flavours o…
The self-coherent camera as a focal plane fine phasing sensor
Pierre Janin-Potiron, Patrice Martinez, Pierre Baudoz +1
Direct imaging of Earth-like exoplanets requires high contrast imaging capability and high angular resolution. Primary mirror segmentation is a key technological solution for large…
Laboratory validation of the dual-zone phase mask coronagraph in broadband light at the high-contrast imaging THD-testbed
J. R. Delorme, M. N'Diaye, R. Galicher +6
Specific high contrast imaging instruments are mandatory to characterize circumstellar disks and exoplanets around nearby stars. Coronagraphs are commonly used in these facilities…
Focal plane wavefront sensor achromatization : The multireference self-coherent camera
J. -R. Delorme, R. Galicher, P. Baudoz +3
High contrast imaging and spectroscopy provide unique constraints for exoplanet formation models as well as for planetary atmosphere models. But this can be challenging because of…
