Simultaneous phase and amplitude aberration sensing with a liquid-crystal vector-Zernike phase mask
David S. Doelman, Fedde Fagginger Auer, Michael J. Escuti +1
We present an enhanced version of the Zernike wavefront sensor, that simultaneously measures phase and amplitude aberrations. The 'vector-Zernike' wavefront sensor consists of a pa…
Fully broadband vAPP coronagraphs enabling polarimetric high contrast imaging
Steven P. Bos, David S. Doelman, Jos de Boer +4
We present designs for fully achromatic vector Apodizing Phase Plate (vAPP) coronagraphs, that implement low polarization leakage solutions and achromatic beam-splitting, enabling…
WIRC+Pol: a low-resolution near-infrared spectropolarimeter
Samaporn Tinyanont, Maxwell A. Millar-Blanchaer, Ricky Nilsson +14
WIRC+Pol is a newly commissioned low-resolution (R~100), near-infrared (J and H band) spectropolarimetry mode of the Wide-field InfraRed Camera (WIRC) on the 200-inch Hale Telescop…
The Single-mode Complex Amplitude Refinement (SCAR) coronagraph: II. Lab verification, and toward the characterization of Proxima b
S. Y. Haffert, E. H. Por, C. U. Keller +4
We present the monochromatic lab verification of the newly developed SCAR coronagraph that combines a phase plate (PP) in the pupil with a microlens-fed single-mode fiber array in…
