A quantitative comparison of amplitude versus intensity interferometry for astronomy
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).

Liquid crystal based spectral control for applications in optical communication and metrology
Results in Optics, 2020 The molecules of nematic liquid crystals (LCs), aligned in one average direction, constitute a birefringent medium. The molecules in nematic LCs of positive anisotropy (ne>no) get aligned in the direction of applied electric field due to the induced ...

Detection of Periodic Disturbances in LOFAR Calibration Solutions
Remote 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

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.
