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

open access: yesGround-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.

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

open access: yesChemistry–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

Far-infrared polarimeter with very low instrumental polarization

open access: yesSPIE 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).

Soft X-Ray Polarimeter: Potential Instrumentation and Observations

open access: yesActa 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

open access: yesAtmospheric Measurement Techniques, 2023
Abstract. 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).

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

open access: yesMonthly 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.

A Multipurpose Scanning Spectral Polarimeter (SSP): Instrument Description and Sample Results

open access: yesJournal of Atmospheric and Oceanic Technology, 2000
Abstract This paper describes the design and characteristics of a scanning spectral polarimeter designed to measure spectral radiances and fluxes in the range between 0.4 and 4.0 μm. The instrument characteristics are described, and the procedures to calibrate the unpolarized radiances and fluxes in the spectral range from 0.4 to 1.1 μm are discussed ...
