Real-time control and data standardization on various telescopes and benches
Nour Skaf, Rebecca Jensen-Clem, Aaron Hunter +19
Real-time control (RTC) is pivotal for any Adaptive Optics (AO) system, including high-contrast imaging of exoplanets and circumstellar environments. It is the brain of the AO syst…
Deepest limits on scattered light emission from the Epsilon Eridani inner debris disk with HST/STIS
Sai Krishanth P. M., Ewan S. Douglas, Ramya M. Anche +9
Epsilon Eridani ( Eri) is one of the first debris disk systems detected by the Infrared Astronomical Satellite (IRAS). However, the system has thus far eluded detection in scatt…
Optical alignment of contamination-sensitive Far-Ultraviolet spectrographs for Aspera SmallSat mission
Aafaque R. Khan, Erika Hamden, Haeun Chung +48
Aspera is a NASA Astrophysics Pioneers SmallSat mission designed to study diffuse OVI emission from the warm-hot phase gas in the halos of nearby galaxies. Its payload consists of…
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…
Optical modeling for the evaluation of HOWFSC on embedded processors
Kian Milani, Ewan Douglas, Leonid Pogorelyuk +5
The correction of quasi-static wavefront errors within a coronagraphic optical system will be a key challenge to overcome in order to directly image exoplanets in reflected light.…
Modeling and performance analysis of Implicit Electric Field Conjugation with two deformable mirrors applied to the Roman Coronagraph
Kian Milani, Ewan S. Douglas, Sebastiaan Y. Haffert +1
High-order wavefront sensing and control (HOWFSC) is key to create a dark hole region within the coronagraphic image plane where high contrasts are achieved. The Roman Coronagraph…
A Generalized Expression for Accelerating Beamlet Decomposition Simulations
Jaren N. Ashcraft, Ewan S. Douglas, Ramya Anche +7
Paraxial diffraction modeling based on the Fourier transform has seen widespread implementation for simulating the response of a diffraction-limited optical system. For systems whe…
