MSPI: The Multiangle Spectro-Polarimetric Imager
نویسنده
چکیده
The Multiangle SpectroPolarimetric Imager (MSPI) is a new type of polarimetric camera jointly designed and fabricated by the University of Arizona and the Jet Propulsion Laboratory. Developed for aerosol measurements from space, MSPI is well-suited for a variety of Stokes imaging applications from the UV through the Visible, NIR, and SWIR which demand polarimetric precision of better than 0.5% at time scales between DC and 25 Hz. The telescope is a three-mirror off-axis anastigmat, and images are built up through a pushbroom scan. Polarization modulation is provided by a novel implementation of dual photoelastic modulators set between quarterwave plates. The polarization is analyzed by an integrated assembly of rows of linear polarizers and dielectric filters applied directly above the focal plane array. [1]

UV-SWIR Achromatic Quarter Wave Retarder for the Multiangle Spectropolarimetric Imager (MSPI)
We describe the design, fabrication, and testing of an achromatic, athermalized quarterwave retarder, a key component for the Multiangle Spectro-Polarimetric Imager (MSPI), which is a candidate for the Aerosol-Cloud-Ecosystem (ACE) mission. The desired wavelength range of the instrument encompasses the UV, visible, near IR, and shortwave IR, extending from 355 nm to 2130 nm, with polarimetric c...

We have assembled a wide spectral range, allelectronic spectro-polarimetric imager utilizing an acousto-optic tunable filter (AOTF), a liquid crystal variable retardation plate, and real-time, softwareadaptable signature masks. This combination of rapidly adjustable parameters allows operation at 30/sec. frame rate, and near real time adaptability to changing target signatures. The spectral cap...

We have built a portable spectro-polarimetric machine vision system that operates at video frame rates. Our system contains only electronically controllable components, including an imaging acousto-optic tunable filter (AOTF), a phase retarder, acceptance and imaging optics, and a standard CCD-based camera. The device operates like an ordinary camera, except that a computer controls the spectra...
متن کاملExploration of a Polarized Surface Bidirectional Reflectance Model Using the Ground-Based Multiangle SpectroPolarimetric Imager
Accurate characterization of surface reflection is essential for retrieval of aerosols using downward-looking remote sensors. In this paper, observations from the Ground-based Multiangle SpectroPolarimetric Imager (GroundMSPI) are used to evaluate a surface polarized bidirectional reflectance distribution function (PBRDF) model. GroundMSPI is an eight-band spectropolarimetric camera mounted on ...
