Simulation results for Robo-AO-2 using HAPA: a wavefront sensing technique for improving the adaptive optics correction of fainter stars
Ruihan Zhang, Christoph Baranec, Marcos A. van Dam +3
Direct imaging of exoplanets allows us to measure positions and chemical signatures of exoplanets. Given the limited resources for space observations where the atmosphere is absent…
In-lab and On-sky Closed-loop Results of Adaptive Secondary Mirrors with TNO's Hybrid Variable Reluctance Actuators
Ruihan Zhang, Max Baeten, Mark R. Chun +8
We performed closed-loop lab testing of large-format deformable mirrors (DMs) with hybrid variable reluctance actuators. TNO has been developing the hybrid variable reluctance actu…
Commissioning results from the Robo-AO-2 facility for rapid visible and near-infrared AO imaging
Christoph Baranec, James Ou, Reed Riddle +16
We installed the next-generation automated laser adaptive optics system, Robo-AO-2, on the University of Hawaii 2.2-m telescope on Maunakea in 2023. We engineered Robo-AO-2 to deli…
