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

Reviews 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]

New 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).

A Robust Interferometry Against Imperfections Base on Weak Value Amplification [PDF]

Phys. Rev. A 97, 063818 (2018), 2018
The optical interferometry has been widely used in various high precision applications. Usually, the minimum precision of an interferometry is limited by various technique noises in practice. To suppress such kind of noises, we propose a novel scheme, which combines the weak measurement with the standard interferometry. The proposed scheme dramatically

Probing non-Abelian statistics with Majorana fermion interferometry in spin-orbit-coupled semiconductors [PDF]

Phys. Rev. B 84, 085109 (2011), 2010
The list of quantum mechanical systems with non-Abelian statistics has recently been expanded by including generic spin-orbit-coupled semiconductors e.g., InAs) in proximity to a s-wave superconductor. Demonstration of the anyonic statistics using Majorana fermion interferometry in this system is a necessary first step towards topological quantum ...

Chirped-pulse interferometry with finite frequency correlations [PDF]

Proc. 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]

Phys. 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 ...

Space-borne Bose–Einstein condensation for precision interferometry [PDF]

Nature, 2018
Owing to the low-gravity conditions in space, space-borne laboratories enable experiments with extended free-fall times. Because Bose–Einstein condensates have an extremely low expansion energy, space-borne atom interferometers based on Bose–Einstein ...

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

Optical 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 ...
