Differential Double Blind Fourier Holography (diff-DBFH)
Oren Pedatzur, David T. Chuss
High-performance optical systems, including space telescopes, require wavefront-sensing and correction capabilities to achieve resolution near the diffraction limit. Existing wavef…
High-Efficiency and Low-Noise Detectors for the Upgraded CLASS 90 GHz Focal Plane
Carolina Núñez, John W. Appel, Rahul Datta +22
We present the in-lab and on-sky performance for the upgraded 90 GHz focal plane of the Cosmology Large Angular Scale Surveyor (CLASS), which had four of its seven detector wafers…
Design and characterization of a 60-cm reflective half-wave plate for the CLASS 90 GHz band telescope
Rui Shi, Michael K. Brewer, Carol Yan Yan Chan +14
Front-end polarization modulation enables improved polarization measurement stability by modulating the targeted signal above the low-frequency drifts associated with atmosph…
CLASS Observations of Atmospheric Cloud Polarization at Millimeter Wavelengths
Yunyang Li, John W. Appel, Charles L. Bennett +21
The dynamic atmosphere imposes challenges to ground-based cosmic microwave background observation, especially for measurements on large angular scales. The hydrometeors in the atmo…
Cosmology Large Angular Scale Surveyor (CLASS): 90 GHz Telescope Pointing, Beam Profile, Window Function, and Polarization Performance
Rahul Datta, Michael K. Brewer, Jullianna Denes Couto +31
The Cosmology Large Angular Scale Surveyor (CLASS) is a telescope array that observes the cosmic microwave background (CMB) over ~75% of the sky from the Atacama Desert, Chile, at…
On-sky performance of new 90 GHz detectors for the Cosmology Large Angular Scale Surveyor (CLASS)
Carolina Núñez, John W. Appel, Michael K. Brewer +18
The Cosmology Large Angular Scale Surveyor (CLASS) is a polarization-sensitive telescope array located at an altitude of 5,200 m in the Chilean Atacama Desert and designed to measu…
