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…
Developing post-coronagraphic, high-resolution spectroscopy for terrestrial planet characterization on ELTs
N. Jovanovic, O. Guyon, T. Kotani +12
Spectroscopic observations are extremely important for determining the composition, structure, and surface gravity of exoplanetary atmospheres. High resolution spectroscopy of the…
On-sky closed loop correction of atmospheric dispersion for high-contrast coronagraphy and astrometry
Prashant Pathak, Olivier Guyon, Nemanja Jovanovic +6
Adaptive optic (AO) systems delivering high levels of wavefront correction are now common at observatories. One of the main limitations to image quality after wavefront correction…
Demonstration of broadband contrast at 1.2 /D and greater for the EXCEDE Starlight Suppression System
Dan Sirbu, Sandrine J. Thomas, Ruslan Belikov +8
The EXoplanetary Circumstellar Environments and Disk Explorer (EXCEDE) science mission concept uses a visible-wavelength Phase-Induced Amplitude Apodization (PIAA) coronagraph to e…
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…
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…
