Lyot-based Ultra-Fine Pointing Control System for Phase Mask Coronagraphs
Garima Singh, Frantz Martinache, Pierre Baudoz +3
High performance coronagraphic imaging at small inner working angle requires efficient control of low order aberrations. The absence of accurate pointing control at small separatio…
SCExAO as a precursor to an ELT exoplanet direct imaging instrument
Nemanja Jovanovic, Olivier Guyon, Frantz martinache +11
The Subaru Coronagraphic Extreme AO (SCExAO) instrument consists of a high performance Phase Induced Amplitude Apodisation (PIAA) coronagraph combined with an extreme Adaptive Opti…
The Subaru Coronagraphic Extreme Adaptive Optics Imager: First Results and On-Sky Performance
Thayne Currie, Olivier Guyon, Frantz Martinache +6
We present new on-sky results for the Subaru Coronagraphic Extreme Adaptive Optics imager (SCExAO) verifying and quantifying the contrast gain enabled by key components: the closed…
