On-sky results from REDWOODS, a platform at Lick/ShaneAO for testing second stage AO technologies
Benjamin L. Gerard, Dominic F. Sanchez, Aditya R. Sengupta +11
REDWOODS is a new sub-testbed within the Shane Adaptive Optics (AO) system at Lick observatory, developed to test second stage AO wavefront sensing and control technologies, includ…
WaveDriver: a Laser Guide Star AO System for HWO
Benjamin L. Gerard, Alex Geringer-Sameth, Aditya R. Sengupta +7
Habitable Worlds Observatory (HWO) presents a key challenge for technology development in the coming years, requiring a more stable system than \textit{JWST}. WaveD…
WaveDriver: a Laser Guide Star AO System for HWO
Benjamin L. Gerard, Alex Geringer-Sameth, Aditya R. Sengupta +16
HWO's Tier 1 Contrast Stability Technology Gap presents a key challenge for technology development in the coming years, requiring to a >100x more stable system than JWST. WaveDrive…
Control algorithms for dual-wavefront sensor single-conjugate adaptive optics
Aditya R. Sengupta, Lisa A. Poyneer, Benjamin L. Gerard +2
High-contrast imaging systems using active control with adaptive optics (AO) are often limited by non-common path (NCP) aberrations that are seen only at the final science image. A…
The Focal-plane Actualized Shifted Technique Realized for a Shack Hartmann Wavefront Sensor (fastrSHWFS)
Benjamin L. Gerard, Aaron Lemmer, Bautista R. Fernandez +6
Astronomical adaptive optics (AO) is a critical approach to enable ground-based diffraction-limited imaging and high contrast science, with the potential to enable habitable exopla…
