Paper Abstract

Hyperspectral polarimetry is demonstrated to measure the spectrum and polarization state of a scene. This information is important to identify material properties for applications such as remote sensing and agricultural monitoring, among others. We report the design and performance of a ruggedized, field deployable Hyperspectral Polarimeter Imaging (HPI) system over the VIS to NIR range (450-800 nm). An entrance slit was used to sample a scene in a pushbroom scanning mode, sampling over a 30 degree vertical by 110 degree horizontal field of view. Furthermore, athermalized achromatic retarders were implemented in a channel spectrum generator to measure the linear Stoke vectors. This paper reports the mechanical and optical layout of the system and its peripherals. We present preliminary spectral and polarimetry calibration techniques as well as testing results in field environments.
