Active focal-plane coronagraphy with liquid-crystal spatial-light modulators: Broadband contrast performance in the visible
J. G. Kuhn, P. Patapis
The technological progress in spatial-light modulators (SLM) technology has made it possible to use those devices as programmable active focal-plane phase coronagraphic masks, open…
Design of the Life Signature Detection Polarimeter LSDpol
Christoph U. Keller, Frans Snik, C. H. Lucas Patty +11
Many biologically produced chiral molecules such as amino acids and sugars show a preference for left or right handedness (homochirality). Light reflected by biological materials s…
RISTRETTO: a pathfinder instrument for exoplanet atmosphere characterization
Bruno Chazelas, Christophe Lovis, Nicolas Blind +8
We introduce the RISTRETTO instrument for ESO VLT, an evolution from the original idea of connecting the SPHERE high-contrast facility to the ESPRESSO spectrograph (Lovis et al 201…
A snapshot full-Stokes spectropolarimeter for detecting life on Earth
Frans Snik, Christoph U. Keller, David S. Doelman +8
We present the design of a point-and-shoot non-imaging full-Stokes spectropolarimeter dedicated to detecting life on Earth from an orbiting platform like the ISS. We specifically a…
A simple optimized amplitude pupil mask for attempting to direct imaging of Proxima b with SPHERE/ZIMPOL at VLT
Polychronis Patapis, Jonas Kühn, Hans Martin Schmid
Proxima b is a terrestrial exoplanet orbiting in the habitable zone of our closest star Proxima Centauri. The separation between the planet and the star is about 40 mas and this is…
SLM-based Digital Adaptive Coronagraphy: Current Status and Capabilities
Jonas Kuhn, Polychronis Patapis, Xin Lu +1
Active coronagraphy is deemed to play a key role for the next generation of high-contrast instruments, notably in order to deal with large segmented mirrors that might exhibit time…
