Active focal plane phase mask coronagraphy with a discrete pixelated device: I. Study of the theoretical performance trade space
Liurong Lin, Axel Potier, Ruben Tandon +2
Recent advances in high-contrast exoplanet imaging instrumentation have introduced the concept of adaptive coronagraphy. For example, liquid-crystal-on-silicon spatial light modula…
The PLACID active coronagraphic imager instrument: commissioning status
Ruben Tandon, Lucas Marquis, Liurong Lin +9
The world's first adaptive stellar coronagraph, the Programmable Liquid-crystal Active Coronagraphic Imager for the 4-m DAG telescope (PLACID) uses a spatial light modulator operat…
Design and implementation of an SLM-driven coherent differential imaging scheme
L. Lin, L. Marquis, R. Tandon +1
Direct imaging of exoplanets from the ground remains fundamentally limited by fast-evolving post-adaptive optics (AO) residual wavefront errors, and by quasi-static speckles arisin…
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…
Spectropolarimetry of life: airborne measurements from a hot air balloon
Willeke Mulder, C. H. Lucas Patty, Stefano Spadaccia +6
Does life exist outside our Solar System? A first step towards searching for life outside our Solar System is detecting life on Earth by using remote sensing applications. One powe…
Directional aspects of vegetation linear and circular polarization biosignatures
C. H. Lucas Patty, Antoine Pommerol, Jonas G. Kühn +2
Homochirality is a generic and unique property of all biochemical life and is considered a universal and agnostic biosignature. Upon interaction with unpolarized light, homochirali…
Three years of harvest with the vector vortex coronagraph in the thermal infrared
Olivier Absil, Dimitri Mawet, Mikael Karlsson +25
For several years, we have been developing vortex phase masks based on sub-wavelength gratings, known as Annular Groove Phase Masks. Etched onto diamond substrates, these AGPMs are…
The Subaru Coronagraphic Extreme Adaptive Optics system: enabling high-contrast imaging on solar-system scales
N. Jovanovic, F. Martinache, O. Guyon +35
The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument is a multipurpose high-contrast imaging platform designed for the discovery and detailed characterization of ex…
