Modern optical astronomy: technology and impact of interferometry [PDF]

open access: yesReviews of Modern Physics, 2002
The present `state of the art' and the path to future progress in high spatial resolution imaging interferometry is reviewed. The review begins with a treatment of the fundamentals of stellar optical interferometry, the origin, properties, optical effects of turbulence in the Earth's atmosphere, the passive methods that are applied on a single ...

A quantitative comparison of amplitude versus intensity interferometry for astronomy [PDF]

open access: yesNew Journal of Physics, 2022
Astronomical imaging can be broadly classified into two types. The first type is amplitude interferometry, which includes conventional optical telescopes and very large baseline interferometry (VLBI).

Interferometry concepts [PDF]

open access: yesEAS Publications Series, 2014
This paper serves as an introduction to the current book. It provides the basic notions of long-baseline optical/infrared interferome-try prior to reading all the subsequent chapters, and is not an extended introduction to the field.Comment: 35 pages, 13

Fluorescence interferometry [PDF]

open access: yesPhysical Review A, 2010
We describe an interferometer based on fluorescent emission of radiation of two qubits in quasi-one-dimensional modes. Such a system can be readily realized with dipole emitters near conducting surface-plasmonic nanowires or with superconducting qubits ...

Chirped-pulse interferometry with finite frequency correlations [PDF]

open access: yesProc. SPIE, Vol. 7465, 74650N (2009), 2009
Chirped-pulse interferometry is a new interferometric technique encapsulating the advantages of the quantum Hong-Ou-Mandel interferometer without the drawbacks of using entangled photons. Both interferometers can exhibit even-order dispersion cancellation which allows high resolution optical delay measurements even in thick optical samples.

Landau-Zener-Stuckelberg interferometry [PDF]

open access: yesPhys. Rept. 492, 1 (2010), 2009
A transition between energy levels at an avoided crossing is known as a Landau-Zener transition. When a two-level system (TLS) is subject to periodic driving with sufficiently large amplitude, a sequence of transitions occurs. The phase accumulated between transitions (commonly known as the Stuckelberg phase) may result in constructive or destructive ...

CMB interferometry [PDF]

open access: yesProceedings of Resolving The Sky - Radio Interferometry: Past, Present and Future — PoS(RTS2012), 2012
Interferometry has been a very successful tool for measuring anisotropies in the cosmic microwave background. Interferometers provided the first constraints on CMB anisotropies on small angular scales (l~10000) in the 1980s and then in the late 1990s and

Stellar Intensity Interferometry: Astrophysical targets for sub-milliarcsecond imaging [PDF]

open access: yesOptical and Infrared Interferometry II (W.C.Danchi, F.Delplancke, J.K.Rajagopal, eds.), Proc. SPIE vol. 7734, 77340A (2010), 2010
Intensity interferometry permits very long optical baselines and the observation of sub-milliarcsecond structures. Using planned kilometric arrays of air Cherenkov telescopes at short wavelengths, intensity interferometry may increase the spatial resolution achieved in optical astronomy by an order of magnitude, inviting detailed studies of the shapes ...
