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…
SCExAO, an instrument with a dual purpose: perform cutting-edge science and develop new technologies
Julien Lozi, Olivier Guyon, Nemanja Jovanovic +31
The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument is an extremely modular high-contrast instrument installed on the Subaru telescope in Hawaii. SCExAO has a dual…
Multiplexed Holographic Aperture Masking with liquid-crystal geometric phase masks
David S. Doelman, Peter Tuthill, Barnaby Norris +5
Sparse Aperture Masking (SAM) allows for high-contrast imaging at small inner working angles, however the performance is limited by the small throughput and the number of baselines…
Review of high-contrast imaging systems for current and future ground-based and space-based telescopes III. Technology opportunities and pathways
Frans Snik, Olivier Absil, Pierre Baudoz +30
The Optimal Optical CoronagraphWorkshop at the Lorentz Center in September 2017 in Leiden, the Netherlands gathered a diverse group of 25 researchers working on exoplanet instrumen…
Review of high-contrast imaging systems for current and future ground-based and space-based telescopes II. Common path wavefront sensing/control and Coherent Differential Imaging
Nemanja Jovanovic, Olivier Absil, Pierre Baudoz +28
The Optimal Optical Coronagraph (OOC) Workshop held at the Lorentz Center in September 2017 in Leiden, the Netherlands, gathered a diverse group of 25 researchers working on exopla…
