Wavefront Profiling via correlation of GLAO open loop telemetry
Eden A. McEwen, Ryan Dungee, Mark Chun +3
Adaptive Optics (AO) used in ground based observatories can be strengthened in both design and algorithms by a more detailed understanding of the atmosphere they seek to correct. N…
Beyond CCDs: Characterization of sCMOS detectors for optical astronomy
Aditya Khandelwal, Sarik Jeram, Ryan Dungee +7
Modern scientific complementary metal-oxide semiconductor (sCMOS) detectors provide a highly competitive alternative to charge-coupled devices (CCDs), the latter of which have hist…
DO-CRIME: Dynamic On-sky Covariance Random Interaction Matrix Evaluation, a novel method for calibrating adaptive optics systems
Olivier Lai, Mark Chun, Ryan Dungee +2
Adaptive optics systems require a calibration procedure to operate, whether in closed loop or even more importantly in forward control. This calibration usually takes the form of a…
On the Feasibility of Using a Laser Guide Star Adaptive Optics System in the Daytime
Ryan Dungee, Mark Chun, Yutaka Hayano
We investigate the use of ultra-narrow band interference filters to enable daytime use of sodium laser guide star adaptive optics systems. Filter performance is explored using theo…
