RISTRETTO: coronagraph and AO designs enabling High Dispersion Coronagraphy at 2 lambda/D
N. Blind, B. Chazelas, J. Kühn +13
RISTRETTO is the evolution of the original idea of coupling the VLT instruments SPHERE and ESPRESSO, aiming at High Dispersion Coronagraphy. RISTRETTO is a visitor instrument that…
High contrast at small separation -- II. Impact on the dark hole of a realistic optical set-up with two deformable mirrors
M. Beaulieu, P. Martinez, L. Abe +3
Future large space- or ground-based telescopes will offer the resolution and sensitivity to probe the habitable zone of a large sample of nearby stars for exo-Earth imaging. To thi…
High-contrast imaging at small separation: impact of the optical configuration of two deformable mirrors on dark holes
M. Beaulieu, L. Abe, P. Martinez +3
The direct detection and characterization of exoplanets will be a major scientific driver over the next decade, involving the development of very large telescopes and requires high…
Laser-guide-stars used for cophasing broad capture ranges
Martinez, Janin-Potiron
Segmented primary mirrors are indispensable to master the steady increase in spatial resolution. Phasing optics systems must reduce segment misalignments to guarantee the high opti…
