Exploring the NRO Opportunity for a Hubble-sized Wide-field Near-IR Space Telescope -- NEW WFIRST
Alan Dressler, David Spergel, Matt Mountain +24
We discuss scientific, technical and programmatic issues related to the use of an NRO 2.4m telescope for the WFIRST initiative of the 2010 Decadal Survey. We show that this impleme…
Kalman Filter Estimation for Focal Plane Wavefront Correction
Tyler D. Groff, N. Jeremy Kasdin
Space-based coronagraphs for future earth-like planet detection will require focal plane wavefront control techniques to achieve the necessary contrast levels. These correction alg…
Broadband Focal Plane Wavefront Control of Amplitude and Phase Aberrations
Tyler D. Groff, N. Jeremy Kasdin, Alexis Carlotti +1
The Stroke Minimization algorithm developed at the Princeton High Contrast Imaging Laboratory has proven symmetric dark hole generation using minimal stroke on two deformable mirro…
Conceptual Design of the Coronagraphic High Angular Resolution Imaging Spectrograph (CHARIS) for the Subaru Telescope
Mary Anne Peters, Tyler Groff, N. Jeremy Kasdin +14
Recent developments in high-contrast imaging techniques now make possible both imaging and spectroscopy of planets around nearby stars. We present the conceptual design of the Coro…
Scientific Design of a High Contrast Integral Field Spectrograph for the Subaru Telescope
Michael W. McElwain, Timothy D. Brandt, Markus Janson +18
Ground-based telescopes equipped with adaptive-optics (AO) systems and specialized science cameras are now capable of directly detecting extrasolar planets. We present the expected…
