Field of View Based Optimization of Aspheric Designed Geometric-Phase Doublet Lenses
Kathryn J. Hornburg, Xiao Xiang, Michael W. Kudenov +1
Here we study aspheric phase pattern geometric-phase lenses through the design of doublet lenses in Zemax Optic Studio and in MATLAB using a simple ray tracing code. The solutions…
First light of a holographic aperture mask: Observation at the Keck OSIRIS Imager
David S. Doelman, Joost P. Wardenier, Peter Tuthill +8
We report on the design, construction, and commissioning of a prototype aperture masking technology implemented at the Keck OSIRIS Imager: the holographic aperture mask. Holographi…
The vector-apodizing phase plate coronagraph: design, current performance, and future development
D. S. Doelman, F. Snik, E. H. Por +50
Over the last decade, the vector-apodizing phase plate (vAPP) coronagraph has been developed from concept to on-sky application in many high-contrast imaging systems on 8-m class t…
Minimizing the polarization leakage of geometric-phase coronagraphs with multiple grating pattern combinations
David S. Doelman, Emiel H. Por, Garreth Ruane +2
The design of liquid-crystal diffractive phase plate coronagraphs for ground-based and space-based high-contrast imaging systems is limited by the trade-off between spectral bandwi…
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…
