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…
Simulations of polarimetric observations of debris disks through the Roman Coronagraph Instrument
Ramya Manjunath Anche, Ewan S. Douglas, Kian Milani +2
The Roman coronagraph instrument will demonstrate high-contrast imaging technology, enabling the imaging of faint debris disks, the discovery of inner dust belts, and planets. Pola…
Practical limits on Nanosatellite Telescope Pointing: The Impact of Disturbances and Photon Noise
Ewan S. Douglas, Kevin Tracy, Zachary Manchester
Accurate and stable spacecraft pointing is a requirement of many astronomical observations. Pointing particularly challenges nanosatellites because of an unfavorable surface area t…
Demonstration of magnetic and light-controlled actuation of a photomagnetically actuated deformable mirror for wavefront control
Amit Kumar Jha, Ewan S. Douglas, Meng Li +2
Deformable Mirrors (DMs) have wide applications ranging from astronomical imaging to laser communications and vision science. However, they often require bulky multi-channel cables…
Sensitivity of the Roman Coronagraph Instrument to Exozodiacal Dust
Ewan S Douglas, John Debes, Bertrand Mennesson +7
Exozodiacal dust, warm debris from comets and asteroids in and near the habitable zone of stellar systems, reveals the physical processes that shape planetary systems. Scattered li…
