Alignment of three mirror anastigmat telescopes using a multilayered stochastic parallel gradient descent algorithm
Solvay Blomquist, Heejoo Choi, Hyukmo Kang +4
When a telescope doesn't reach a reasonable point spread function on the detector or detectable wavefront quality after initial assembly, a coarse phase alignment on-sky is crucial…
Approaches to developing tolerance and error budget for active three mirror anastigmat space telescopes
Heejoo Choi, Young-Sik Kim, Hyukmo Kang +6
The size of the optics used in observatories is often limited by fabrication, metrology, and handling technology, but having a large primary mirror provides significant benefits fo…
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…
Compact Three Mirror Anastigmat Space Telescope Design using 6.5m Monolithic Primary Mirror
Daewook Kim, Heejoo Choi, Ewan S. Douglas
The utilization of a 6.5m monolithic primary mirror in a compact three-mirror anastigmat (TMA) telescope design offers unprecedented capabilities to accommodate various next genera…
The space coronagraph optical bench (SCoOB): 2. wavefront sensing and control in a vacuum-compatible coronagraph testbed for spaceborne high-contrast imaging technology
Kyle Van Gorkom, Ewan S. Douglas, Jaren N. Ashcraft +9
The 2020 Decadal Survey on Astronomy and Astrophysics endorsed space-based high contrast imaging for the detection and characterization of habitable exoplanets as a key priority fo…
The Space Coronagraph Optical Bench (SCoOB): 1. Design and Assembly of a Vacuum-compatible Coronagraph Testbed for Spaceborne High-Contrast Imaging Technology
Jaren N. Ashcraft, Heejoo Choi, Ewan S. Douglas +14
The development of spaceborne coronagraphic technology is of paramount importance to the detection of habitable exoplanets in visible light. In space, coronagraphs are able to bypa…
