NIRC2-Pol: First Light of Near-Infrared Polarimetry on Keck II
Briley L. Lewis, Manxuan Zhang, Maxwell A. Millar-Blanchaer +21
NIRC2, the Near Infrared Camera 2 on the Keck II telescope, was recently upgraded with a new suite of polarimetric observing modes. The new polarimetry modes (referred to as NIRC2-…
Enabling Quantitative Polarimetry for Keck/NIRC2: Preliminary Mueller Matrix Model Calibration
Manxuan Zhang, Briley L. Lewis, Maxwell A. Millar-Blanchaer +27
The Keck/NIRC2 infrared imager was upgraded in 2025 with dual-beam polarimetric observing modes spanning approximately 1.1--4.1 microns (JHKL' bands). We present a preliminary JHK…
Ground control to major time-lag: on-sky results of data-driven predictive wavefront control at Keck Observatory
Jules Fowler, Rebeca Jensen-Clem, Sylvain Cetre +12
Directly imaging and characterizing exoplanets requires extreme adaptive optics (XAO), which achieves exquisite wavefront correction over a small (<5") field of view. Temporal erro…
Reconstruction methods for the phase-shifted Zernike wavefront sensor
Vincent Chambouleyron, Mahawa Cissé, Maïssa Salama +8
The Zernike wavefront sensor (ZWFS) stands out as one of the most sensitive optical systems for measuring the phase of an incoming wavefront, reaching photon efficiencies close to…
Adapting the pyramid wavefront sensor for pupil fragmentation of the ELT class telescopes
Nicolas Levraud, Vincent Chambouleyron, Olivier Fauvarque +8
The next generation of Extremely Large Telescope (24 to 39m diameter) will suffer from the so-called "pupil fragmentation" problem. Due to their pupil shape complexity (segmentatio…
