Single-Shot On-Axis Fizeau Polarization Phase-Shifting Digital Holography for Complex-Valued Dynamic Object Imaging

open access: yesPhotonics, 2022
Digital holography assisted with inline phase-shifting methods has the benefit of a large field of view and a high resolution, but it is limited in dynamic imaging due to sequential detection of multiple holograms.

Detection of Periodic Disturbances in LOFAR Calibration Solutions

open access: yesRemote Sensing, 2022
The Earth’s ionosphere is a highly variable medium on a wide range of spatio-temporal scales. The responsiveness of plasma to the geomagnetic field and its changes gives rise to anisotropy, which may introduce wave-like characteristics while scanning the

Landau-Zener-Stuckelberg interferometry [PDF]

open access: yes, 2010
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.

Broadband spectral shaping using nematic liquid crystal

open access: yesResults in Physics, 2019
We demonstrate what is, to our knowledge, the first implementation of nematic liquid crystal (LC) for spectral shaping of broadband light fields. A LC cell of several microns thickness is placed between a polarizer and an analyzer.

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

open access: yes, 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 ...

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

open access: yes, 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 ...

Narrow linewidth single laser source system for onboard atom interferometry [PDF]

open access: yes, 2014
A compact and robust laser system for atom interferometry based on a frequency-doubled telecom laser is presented. Thanks to an original stabilization architecture on a saturated absorption setup, we obtain a frequency-agile laser system allowing fast ...

Application of GNSS Interferometric Reflectometry for the Estimation of Lake Ice Thickness

open access: yesRemote Sensing, 2020
Lake ice thickness is a sensitive indicator of climate change largely through its dependency on near-surface air temperature and on-ice snow mass (depth and density). Monitoring of the seasonal variations and trends in ice thickness is also important for

Possible detection of nonclassical primordial gravitational waves with Hanbury Brown - Twiss interferometry [PDF]

open access: yes, 2018
We consider possible detection of nonclassicality of primordial gravitational waves (PGWs) by applying Hanbury Brown - Twiss (HBT) interferometry to cosmology.
