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…

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…
