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): 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…
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…
Astronomical Image Processing Benchmark Study for Various Telescope Aperture Shapes
Jyotika Roychowdhury, Kevin Derby, Daewook Kim
We explore the impact of different telescope apertures on the image simulation and deconvolution processes within the context of a synthetic star field. Using HCIPy and Python prog…
Hybrid propagation physics for the design and modeling of astronomical observatories: a coronagraphic example
Jaren N. Ashcraft, Ewan S. Douglas, Daewook Kim +1
For diffraction-limited optical systems an accurate physical optics model is necessary to properly evaluate instrument performance. Astronomical observatories outfitted with corona…
Approaches to lowering the cost of large space telescopes
Ewan S Douglas, Greg Aldering, Greg W. Allan +26
New development approaches, including launch vehicles and advances in sensors, computing, and software, have lowered the cost of entry into space, and have enabled a revolution in…
