Broadband spectral shaping using nematic liquid crystal
Results 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.

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

Reflection effects in interferometry [PDF]
Applied Optics, 1975 Spurious distortions of interference fringes are often encountered in the interferometry of planar solidfluid phase boundaries. These distortions mimic refractive-index variations near the interface and introduce uncertainty in locating the position of the interface on the interferogram.

Absolute Measurement of the Refractive Index of Water by a Mode-Locked Laser at 518 nm
Sensors, 2018 In this paper, we demonstrate a method using a frequency comb, which can precisely measure the refractive index of water. We have developed a simple system, in which a Michelson interferometer is placed into a quartz-glass container with a low expansion ...

Quantum nonlocal double slit interference with partially coherent qubits
Results in PhysicsPartially coherent quantum-entangled beams combine quantum correlation with partial coherence, allowing them to maintain quantum characteristics while being more resistant to distortions caused by random media during propagation.

Effect of oceanic turbulence on the statistical features of electromagnetic optical beam
Results in PhysicsThis work deals with the intricate problem of electromagnetic optical beam propagation through oceanic turbulence. Using the extended Huygens–Fresnel principle, numerically, the behavior of the degree of cross-polarization (DOCP), electromagnetic degree ...
