The WALOPControl software is designed to facilitate comprehensive control and operation of the WALOP (Wide Area Linear Optical Polarimeter) polarimeters, ensuring safe and concurre…
The WALOP-North Instrument I: Optical Design, Filter Design, Calibration
John A. Kypriotakis, Siddharth Maharana, Ramya M. Anche +18
The Wide Area Linear Optical Polarimeter North (WALOP-North) is an optical polarimeter designed for the needs of the PASIPHAE survey. It will be installed on the 1.3m telescope at…
Systems design, assembly, integration and lab testing of WALOP-South Polarimeter
Siddharth Maharana, A. N. Ramaprakash, Chaitanya Rajarshi +28
Wide-Area Linear Optical Polarimeter (WALOP)-South is the first wide-field and survey-capacity polarimeter in the optical wavelengths. On schedule for commissioning in 2024, it wil…
The RoboPol sample of optical polarimetric standards
D. Blinov, S. Maharana, F. Bouzelou +34
Optical polarimeters are typically calibrated using measurements of stars with known and stable polarization parameters. However, there is a lack of such stars available across the…
Bright-Moon Sky as a Wide-Field Linear Polarimetric Flat Source for Calibration
S. Maharana, S. Kiehlmann, D. Blinov +20
Next-generation wide-field optical polarimeters like the Wide-Area Linear Optical Polarimeters (WALOPs) have a field of view (FoV) of tens of arcminutes. For efficient and accurate…
