A Polarized Light Source for the Thermal InfraRed using COTS Wire-Grid Polarizers
This invention is a thin wire filament that can produce polarized thermal emission when heated. Using commercial off the shelf wire-grid elements, a polarized thermal source with an extended spatial profile can be fabricated. Such a well-characterized polarized source in the thermal infrared can be used for the verification, validation, and in-flight...

Incoherent Addition to Generalize Depolarization in Light Scattering Models
Models for polarized light scattering are relevant for creating virtual reality scenes. To get a “real” looking model, the light scattering on the model needs to be simulated correctly to get a realistic model. The polarimetry of objects is measured in the lab, fit to a model, and this model is used to simulate the polarized light scattering...

LWIR Polarimetry for Liquid Phase Discrimination
This technology is a polarimeter in the long-wave infrared domain of the electromagnetic spectrum. These devices are able to distinguish between ice and liquid water. Therefore, this device could serve to observe natural phenomena such as glacial melt or be used in solar system exploration when identifying water, in solid or liquid form, on other celestial...
