Design of the vacuum high contrast imaging testbed for CDEEP, the Coronagraphic Debris and Exoplanet Exploring Pioneer
Erin R. Maier, Ewan S. Douglas, Daewook Kim +26
The Coronagraphic Debris Exoplanet Exploring Payload (CDEEP) is a Small-Sat mission concept for high contrast imaging of circumstellar disks. CDEEP is designed to observe disks in…
Dark zone maintenance results for segmented aperture wavefront error drift in a high contrast space coronagraph
Susan F. Redmond, Laurent Pueyo, Leonid Pogorelyuk +8
Due to the limited number of photons, directly imaging planets requires long integration times with a coronagraphic instrument. The wavefront must be stable on the same time scale,…
Implementation of a broadband focal plane estimator for high-contrast dark zones
Susan F. Redmond, Laurent Pueyo, Leonid Pogorelyuk +6
The characterization of exoplanet atmospheres using direct imaging spectroscopy requires high-contrast over a wide wavelength range. We study a recently proposed focal plane wavefr…
Information-theoretical Limits of Recursive Estimation and Closed-loop Control in High-contrast Imaging
Leonid Pogorelyuk, Laurent Pueyo, Jared R. Males +2
A lower bound on unbiased estimates of wavefront errors (WFE) is presented for the linear regime of small perturbation and active control of a high-contrast region (dark hole). Ana…
A review of simulation and performance modeling for the Roman coronagraph instrument
Ewan S. Douglas, Jaren N. Ashcraft, Ruslan Belikov +10
The Nancy Grace Roman Space Telescope Coronagraph Instrument (CGI) will be capable of characterizing exoplanets in reflected light and will demonstrate space technologies essential…
On the Effects of Pointing Jitter, Actuators Drift, Telescope Rolls and Broadband Detectors in Dark Hole Maintenance and Electric Field Order Reduction
Leonid Pogorelyuk, Laurent Pueyo, N. Jeremy Kasdin
Space coronagraphs are projected to detect exoplantes that are at least 1e10 times dimmer than their host stars. Yet, the actual detection threshold depends on the instrument's wav…
