Kyle Van Gorkom, Ramya M. Anche, Saraswathi Kalyani Subramanian +12
The space coronagraph optical bench (SCoOB) is a high contrast imaging testbed designed to demonstrate starlight suppression techniques at visible wavelengths in a space-like vacuu…
The Space Coronagraph Optical Bench (SCoOB): X. Dark zone maintenance
Saraswathi Kalyani Subramanian, Kyle Van Gorkom, Ramya Anche +12
The Space Coronagraph Optical Bench (SCoOB) is a vacuum high contrast imaging testbed designed to demonstrate starlight suppression at optical wavelengths and obtain contrasts bett…
The Space Coronagraph Optical Bench (SCoOB): 8. end-to-end numerical modeling of the testbed to estimate the contrast limits
Ramya M Anche, Kyle Van Gorkom, Kian Milani +9
The space coronagraph optical bench (SCoOB) at the University of Arizona is a high-contrast imaging testbed designed to operate in a vacuum to obtain a contrast better than 1e-8 in…
Polarization aberration modeling of internal occulters for coronagraphs
Emory L. Jenkins, A J Eldorado Riggs, Ewan S. Douglas +3
The Habitable Worlds Observatory (HWO) is a flagship mission concept proposing to characterize earth-like exoplanets at high contrast with a coronagraph instrument. The most in-dep…
The space coronagraph optical bench (SCoOB): 3. Mueller matrix polarimetry of a coronagraphic exit pupil
Jaren N. Ashcraft, Ewan S. Douglas, Ramya M. Anche +4
High-contrast imaging in the next decade aims to image exoplanets at smaller angular separations and deeper contrasts than ever before. A problem that has recently garnered attenti…
Black Silicon BRDF and Polarization for Coronagraphic Pupil Masks
Emory L. Jenkins, Ramya M. Anche, Kyle J. Van Gorkom +2
Future space observatories will likely have segmented primaries, causing diffraction effects that reduce coronagraph performance. Reflective binary pupil apodizer masks can mitigat…
The Space Coronagraph Optical Bench (SCoOB): 5. End-to-end simulations of polarization aberrations
Ramya M Anche, Kyle J. Van Gorkom, Jaren N. Ashcraft +4
Polarization aberrations originating from the telescope and high-contrast imaging instrument optics introduce polarization-dependent speckles and associated errors in the image pla…
The space coronagraph optical bench (SCoOB): 4. vacuum performance of a high contrast imaging testbed
Kyle Van Gorkom, Ewan S Douglas, Kian Milani +8
The Space Coronagraph Optical Bench (SCoOB) is a high-contrast imaging testbed built to demonstrate starlight suppression techniques at visible wavelengths in a space-like vacuum e…
Poke: An open-source ray-based physical optics platform
Jaren N. Ashcraft, Ewan S. Douglas, Daewook Kim +8
Integrated optical models allow for accurate prediction of the as-built performance of an optical instrument. Optical models are typically composed of a separate ray trace and diff…
Microfabricated pinholes for high contrast imaging testbeds
Emory L. Jenkins, Kyle Van Gorkom, Kevin Derby +2
In order to reach contrast ratios of and beyond, coronagraph testbeds need source optics that reliably emulate nearly-point-like starlight, with microfabricated pinholes…
