Pioneering high contrast science instruments for planet characterization on giant segmented mirror telescopes
N. Jovanovic, O. Guyon, J. Lozi +36
A suite of science instruments is critical to any high contrast imaging facility, as it defines the science capabilities and observing modes available. SCExAO uses a modular approa…
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…
Demonstration of an efficient, photonic-based astronomical spectrograph on an 8-m telescope
N. Jovanovic, N. Cvetojevic, B. Norris +11
We demonstrate for the first time an efficient, photonic-based astronomical spectrograph on the 8-m Subaru Telescope. An extreme adaptive optics system is combined with pupil apodi…
Modal noise in an integrated photonic lantern fed diffraction-limited spectrograph
N. Cvetojevic, N. Jovanovic, S. Gross +9
In an attempt to develop a streamlined astrophotonic instrument, we demonstrate the realization of an all-photonic device capable of both multimode to single mode conversion and sp…
Efficient injection from large telescopes into single-mode fibres: Enabling the era of ultra-precision astronomy
N. Jovanovic, C. Schwab, O. Guyon +9
Photonic technologies offer numerous advantages for astronomical instruments such as spectrographs and interferometers owing to their small footprints and diverse range of function…
Performance of a novel PMMA polymer imaging bundle for field acquisition and wavefront sensing
Samuel Nathan Richards, Sergio Leon-Saval, Michael Goodwin +7
Imaging bundles provide a convenient way to translate a spatially coherent image, yet conventional imaging bundles made from silica fibre optics typically remain expensive with lar…
