Abstract

We have developed and deployed a mast-mounted hyperspectral imaging polarimeter (HIP) and imaged corn fields across multiple diurnal cycles and growing seasons. Using the polarization data, we present results and methods demonstrating the use of polarized bidirectional reflectance distribution functions (pBRDFs) to correct for surface glare when measuring light more deeply scattered from the tissues. This technique reduces time of day, solar incidence angle, and viewing angle as confounding factors for spectral measurements.
