Angular differential kernel phases
Romain Laugier, Frantz Martinache, Nick Cvetojevic +7
To reach its optimal performance, Fizeau interferometry requires that we work to resolve instrumental biases through calibration. One common technique used in high contrast imaging…
Kernel-phase analysis: aperture modeling prescriptions that minimize calibration errors
Frantz Martinache, Alban Ceau, Romain Laugier +5
Kernel-phase is a data analysis method based on a generalization of the notion of closure-phase invented in the context of interferometry, but that applies to well corrected diffra…
Overview of focal plane wavefront sensors to correct for the Low Wind Effect on SUBARU/SCExAO
Sebastien Vievard, Steven Bos, Frederic Cassaing +15
The Low Wind Effect (LWE) refers to a phenomenon that occurs when the wind speed inside a telescope dome drops below m/s creating a temperature gradient near the telescope spide…
Kernel-phase Detection Limits : Hypothesis Testing and the Example of JWST NIRISS Full Pupil Images
Alban Ceau, David Mary, Alexandra Greenbaum +4
The James Webb Space Telescope will offer high-angular resolution observing capability in the near-infrared with masking interferometry on NIRISS, and coronagraphic imaging on NIRC…
Recovering saturated images for high dynamic Kernel-Phase analysis Application to the determination of dynamical masses for the system Gl 494AB
R. Laugier, F. Martinache, A. Ceau +3
Kernel-phase observables extracted from mid- to high-Strehl images are proving to be a powerful tool to probe within a few angular resolution elements of point sources. The attaina…
Calibration of the island effect: Experimental validation of closed-loop focal plane wavefront control on Subaru/SCExAO
Mamadou N'Diaye, Frantz Martinache, Nemanja Jovanovic +5
Island effect (IE) aberrations are induced by differential pistons, tips, and tilts between neighboring pupil segments on ground-based telescopes, which severely limit the observat…
