Sensitivity of an imaging space infrared interferometer.
We study the sensitivities of space infrared interferometers. We formulate the signal-to-noise ratios of infrared images obtained by aperture synthesis in the presence of source shot noise, background shot noise, and detector read noise. We consider the case in which n beams are combined pairwise at n(n-1)/2 detectors and the case in which all the n beams are combined at a single detector. We a...
متن کاملESPRIT – A Far-Infrared Space Interferometer
In the far-infrared (FIR) / THz regime the angular (and often spectral) resolution of observing facilities is still very restricted despite the fact that this frequency range has become of prime importance for modern astrophysics. ALMA (Atacama Large Millimeter Array) with its superb sensitivity and angular resolution will only cover frequencies up to about 1 THz, while the HIFI instrument for ...
متن کاملSensitivity of a Ground-Based Infrared Interferometer for Aperture Synthesis Imaging
Sensitivity limits of ground-based infrared interferometers using aperture synthesis are presented. The motivation of this analysis is to compare an interferometer composed of multiple large telescopes and a single giant telescope with adaptive optics. In deriving these limits, perfect wavefront correction by adaptive optics and perfect cophasing by fringe tracking are assumed. We consider the ...
متن کاملInfrared Imaging of Capella with the IOTA Closure Phase Interferometer
We present infrared aperture synthesis maps produced with the upgraded IOTA interferometer. Michelson interferograms on the close binary system Capella (α Aur) were obtained in the H-band between 2002 November 12 and 16 using the IONIC3 beam combiner. With baselines of 15m ≤ B ≤ 38m, we were able to determine the relative position of the binary components with milliarcsecond (mas) precision and...
متن کاملInfrared point diffraction interferometer.
The point-diffraction interferometer (PDI) is a simple common-path interferometer capable of measuring optical-path differences (OPD) directly. This interferometer, first described by Smartt in 1972,1,2 has since become available commercially for use in the visible spectrum. Currently activity in laser-fusion and high-energy-laser systems has stimulated interest in extending PDI principles to t...
