Abstract
Optical remote sensing systems used to monitor the natural environment often capture scenes that contain partially polarized light. Imagers used for these applications can exhibit a response to partially polarized emitted or reflected light. In this work, the polarization response of several hyperspectral imaging systems manufactured by Resonon, Inc., with spectral sensitivity in the range of 350 – 1700 nm and various spectral sampling rates was measured using a large-aperture, wire-grid polarizer and calibrated light source. The observed polarization response was compensated for after being modeled. The performance of compensation methods was quantified by gathering simultaneous hyperspectral and DoFPcamera images of a partially polarized scene of varying degree of linear polarization in a laboratory setting.
