Visible and Near Infrared Laboratory Demonstration of a Simplified Pyramid Wavefront Sensor
Julien Lozi, Nemanja Jovanovic, Olivier Guyon +4
Wavefront sensing and control are important for enabling one of the key advantages of using large apertures, namely higher angular resolutions. Pyramid wavefront sensors are becomi…
SCExAO, an instrument with a dual purpose: perform cutting-edge science and develop new technologies
Julien Lozi, Olivier Guyon, Nemanja Jovanovic +31
The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument is an extremely modular high-contrast instrument installed on the Subaru telescope in Hawaii. SCExAO has a dual…
From Lab Testing to Science: Applying SAPHIRA HgCdTe L-APD Detectors to Adaptive Optics
Sean Goebel
Due to their high frame rates, high sensitivity, low noise, and low dark current, SAPHIRA detectors provide new capabilities for astronomical observations. The SAPHIRA detector is…
Overview of the SAPHIRA Detector for AO Applications
Sean B. Goebel, Donald N. B. Hall, Olivier Guyon +2
We discuss some of the unique details of the operation and behavior of Leonardo SAPHIRA detectors, particularly in relation to their usage for adaptive optics wavefront sensing. SA…
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…
