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…
Focus diverse phase retrieval testbed development of continuous wavefront sensing for space telescope applications
Hyukmo Kang, Kyle Van Gorkom, Jess Johnson +4
Continuous wavefront sensing on future space telescopes allows relaxation of stability requirements while still allowing on-orbit diffraction-limited optical performance. We consid…
Integrated modeling of wavefront sensing and control for space telescopes utilizing active and adaptive optics
Kevin Z. Derby, Kian Milani, Solvay Blomquist +9
Extreme wavefront correction is required for coronagraphs on future space telescopes to reach 1e-8 or better starlight suppression for the direct imaging and characterization of ex…
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…
Polarimetric modeling and assessment of science cases for Giant Magellan Telescope-Polarimeter (GMT-Pol)
Ramya M Anche, Grant Williams, Hill Tailor +5
Polarization observations through the next-generation large telescopes will be invaluable for exploring the magnetic fields and composition of jets in AGN, multi-messenger transien…
