The Space Infrared Interferometric Telescope (SPIRIT): High-resolution imaging and spectroscopy in the far-infrared
David Leisawitz, Charles Baker, Amy Barger +53
We report results of a recently-completed pre-Formulation Phase study of SPIRIT, a candidate NASA Origins Probe mission. SPIRIT is a spatial and spectral interferometer with an ope…
ExoPTF Science Uniquely Enabled by Far-IR Interferometry: Probing the Formation of Planetary Systems, and Finding and Characterizing Exoplanets
David Leisawitz, Tom Armstrong, Chad Bender +28
By providing sensitive sub-arcsecond images and integral field spectroscopy in the 25 - 400 micron wavelength range, a far-IR interferometer will revolutionize our understanding of…
Mission Concept for the Single Aperture Far-Infrared (SAFIR) Observatory
Dominic J. Benford, Michael J. Amato, John C. Mather +2
The Single Aperture Far-InfraRed (SAFIR) Observatory's science goals are driven by the fact that the earliest stages of almost all phenomena in the universe are shrouded in absorpt…
Wide-field Imaging Interferometry Testbed II: Implementation, Performance, and Plans
S. A. Rinehart, Bradley J. Frey, David T. Leisawitz +6
The Wide-Field Imaging Interferometry Testbed (WIIT) will provide valuable information for the development of space-based interferometers. This laboratory instrument operates at op…
The Wide-Field Imaging Interferometry Testbed III. Metrology Subsystem
D. B. Leviton, B. J. Frey, D. T. Leisawitz +6
In order for data products from WIIT to be as robust as possible, the alignment and mechanical positions of source, receiver, and detector components must be controlled and measure…
The Wide-Field Imaging Interferometry Testbed I: Purpose, Testbed Design, Data, and Synthesis Algorithms
D. Leisawitz, B. J. Frey, D. B. Leviton +6
The Wide-field Imaging Interferometry Testbed (WIIT) was designed to validate, experiment with, and refine the technique of wide field mosaic imaging for optical/IR interferometers…
