Optical aspects of Near-Infrared Imager Spectrometer and Polarimeter instrument (NISP) [PDF]

Ground-based and Airborne Instrumentation for Astronomy VIII, 2020
As a Near-IR instrument to PRL's upcoming 2.5 m telescope, NISP is designed indigeniously at PRL to serve as a multifaceted instrument. Optical, Mechanical and Electronics subsystems are being designed and developed in-house at PRL. It will consist of imaging, spectroscopy and imaging-polarimetry mode in the wavelength bands Y, J, H, Ks i.e.

Far-infrared polarimeter with very low instrumental polarization

SPIE Proceedings, 2003
After a short analysis of the main problems involved in the construction of a Far Infrared polarimeter with very low instrumental noise, we describe the instrument that will be employed at MITO telescope to search for calibration sources and investigate polarization near the CMB anisotropy peaks in the next campaign (Winter 2002-03).

The Open Polarimeter: A High‐Resolution Instrument Made from Inexpensive Optomechanical Parts

Chemistry–Methods, 2020
AbstractThe Open Polarimeter (“Opol”) is a phase‐based, high‐resolution laser polarimeter formed from a small number of inexpensive optomechanical parts. The complete instrument can be assembled from scratch in less than two days for less than US$250, using only a 3D‐printer and a benchtop milling machine. However, despite its low cost, Opol achieves a

Soft X-Ray Polarimeter: Potential Instrumentation and Observations

Acta Polytechnica CTU Proceedings, 2014
We present an instrument design capable of measuring linear X-ray polarization over a broad-band using conventional spectroscopic optics. A set of multilayer-coated flats reflects the dispersed X-rays to the instrument detectors. The intensity variation with position angle is measured to determine three Stokes parameters: I, Q, and U - all as a ...

Pre-launch calibration and validation of the Airborne Hyper-Angular Rainbow Polarimeter (AirHARP) instrument

Atmospheric Measurement Techniques, 2023
The Airborne Hyper-Angular Rainbow Polarimeter (AirHARP) is a new imaging polarimeter instrument capable of sampling a single Earth target from up to 120 viewing angles, in four spectral channels, and in three linear polarization states across a 114° field of view (FOV).

Metasurface‐Enabled Single‐Shot Intensity‐and‐Phase‐Interrogation Surface‐Plasmon‐Resonance Microscopy

Laser &Photonics Reviews, EarlyView.
A metasurface‐enabled full‐Stokes polarimeter is integrated with phase‐interrogated surface plasmon resonance microscopy to enable single‐shot recovery of intensity and differential phase. The non‐interferometric platform supports quantitative refractive‐index and thickness mapping, wavelength‐resolved sensing, and dynamic multi‐channel monitoring ...

High‐purity X‐ray polarimetry at high energies for Mössbauer spectroscopy

Journal of Synchrotron Radiation, EarlyView.
This work extends high‐purity X‐ray polarimetry into the 15–30 keV range, enabling polarization‐filtered synchrotron Mössbauer spectroscopy of higher‐energy nuclear resonances. A proof‐of‐principle experiment at 22.494 keV demonstrates a polarization purity of (1.2 ± 0.5) × 10−8, establishing the feasibility of the approach.High‐purity X‐ray ...

The Calern Asteroid Polarimetric Survey using the Torino polarimeter: assessment of instrument performances and first scientific results [PDF]

Monthly Notices of the Royal Astronomical Society, 2016
A new polarimeter based on the Wedged double Wollaston concept has been built at the Torino Observatory and installed on a 1-meter telescope at the Calern observing station of the "Observatoire de la Côte d'Azur". Its main purpose is to carry out a polarimetric survey of Solar System objects.
