Facility integration of the NASA IRTF adaptive secondary mirror
Ellen Lee, Mark Chun, Michael Connelley +12
IRTF-ASM-1 has been functioning well since its first light in 2024. This adaptive secondary mirror (ASM) was primarily developed to be an on-sky demonstration of the new hybrid var…
Progress report on the integration of the IRTF adaptive secondary mirror
Ellen Lee, Mark Chun, Ruihan Zhang +13
IRTF-ASM-1 is the first on-sky adaptive secondary mirror using the hybrid variable reluctance (HVR) actuators developed by the Netherlands Organization for Applied Scientific Resea…
First laboratory and on-sky results of an adaptive secondary mirror with TNO-style actuators on the NASA Infrared Telescope Facility
Ellen Lee, Mark Chun, Olivier Lai +14
We are developing an adaptive secondary mirror (ASM) that uses a new actuator technology created by the Netherlands Organization for Applied Scientific Research (TNO). The TNO hybr…
V(WF)S: Very Wide Field WaveFront Sensor for GLAO
Olivier Lai, Mark Chun, Stefan Kuiper +7
Adaptive optics is a technique mostly used on large telescopes. It turns out to be challenging for smaller telescopes (0.5~2m) due to the small isoplanatic angle, small subaperture…
