Spectropolarimeter on-board the Aditya-L1: Polarization Modulation and Demodulation
K. Nagaraju, B. Raghavendra Prasad, Bhavana S. Hegde +5
One of the major science goals of the Visible Emission Line Coronagraph (VELC) payload aboard the Aditya-L1 mission is to map the coronal magnetic field topology and the quantitati…
Full Stokes polarimetry using Dual-Frequency Liquid Crystals
K. Nagaraju, D. V. S. Phanindra, S. Krishna Prasad +2
In a dual-frequency liquid crystal (DFLC), when the frequency of the applied voltage is more than a critical value (), the dielectric anisotropy of the material changes from p…
High-resolution, high-sensitivity, ground-based solar spectropolarimetry with a new fast imaging polarimeter
F. A. Iglesias, A. Feller, K. Nagaraju +1
Context. Remote sensing of weak and small-scale solar magnetic fields is of utmost relevance for a number of important open questions in solar physics. This requires the acquisitio…
Smear correction of highly-variable, frame-transfer-CCD images with application to polarimetry
Francisco A. Iglesias, Alex Feller, K. Nagaraju
Image smear, produced by the shutter-less operation of frame transfer CCD detectors, can be detrimental for many imaging applications. Existing algorithms used to numerically remov…
