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…
Coherent Differential Imaging of high-contrast extended sources with VLT/SPHERE
Axel Potier, Raphaël Galicher, Pierre Baudoz +6
High-contrast imaging relies on advanced coronagraphs and adaptive optics (AO) to attenuate the starlight. However, residual aberrations, especially non-common path aberrations bet…
The Programmable Liquid-crystal Active Coronagraphic Imager for the 4-m DAG telescope (PLACID) instrument: installation and commissioning update
Jonas G. Kühn, Ruben Tandon, Lucas Marquis +9
The Programmable Liquid-crystal Active Coronagraphic Imager for the DAG telescope (PLACID) instrument is a novel high-contrast direct imaging facility that was recently installed o…
The Programmable Liquid-crystal Active Coronagraphic Imager for the DAG telescope (PLACID) instrument: On-site status update ahead of first light
Jonas G. Kühn, Laurent Jolissaint, Audrey Baur +8
The Programmable Liquid-crystal Active Coronagraphic Imager for the DAG telescope (PLACID) instrument is a novel high-contrast direct imaging facility that was recently delivered t…
Future exoplanet direct imaging instruments: Simulating spatial light modulator-based pixelated focal-plane coronagraphy
Liurong Lin, Axel Potier, Ruben Tandon +1
The programmable Liquid-crystal Active Coronagraphic Imager for the DAG Telescope (PLACID) instrument will be installed on the Turkish 4-m Telescope by the fall of 2024 and is expe…
Discovery space and science with the PLACID stellar coronagraph
Ruben Tandon, Liurong Lin, Axel Potier +4
The world's first ever ''adaptive stellar coronagraph'' facility will be the PLACID instrument, installed on Turkey's new national observatory 4-m DAG telescope. PLACID incorporate…
