Dual-field imaging polarimeter using liquid crystal variable retarders
Nathan J. Pust,Joseph A. Shaw +1 more
TL;DR: An imaging Stokes-vector polarimeter using liquid crystal variable retarders (LCVRs) has been built and calibrated, and careful design and calibration of the instrument has achieved errors within +/-1.5%.
Radiometric cloud imaging with an uncooled microbolometer thermal infrared camera.
TL;DR: The radiometric calibration is validated and improved through direct comparison with spectrally integrated data from the Atmospheric Emitted Radiance Interferometer, and the Infrared Cloud Imager (ICI) system routinely obtains sky images with radiometric uncertainty less than 0.5 W/(m(2 )sr) for extended deployments in challenging field environments.

Wavelength dependence of the degree of polarization in cloud-free skies: simulations of real environments
Nathan J. Pust,Joseph A. Shaw +1 more
TL;DR: This work simulates the maximum sky DoP of cloud-free skylight using coincident Hyperion satellite observations and AERONET retrievals to provide model inputs and shows large variations in the wavelength dependence of sky polarization across different Earth environments.

Errata: Correcting for focal-plane-array temperature dependence in microbolometer infrared cameras lacking thermal stabilization
TL;DR: In this paper, a method for stabilizing the camera response through software processing is described. But it is based on the difference between the camera's response at a measured temperature and at a reference temperature.

Radiometric calibration of infrared imagers using an internal shutter as an equivalent external blackbody
TL;DR: In this article, a method for stabilizing the camera response through software processing of consecutive images of the scene and images of camera's internal shutter is described, where an image of the shutter is processed so that it appears as if it were viewed through the lens.
