Imaging Polarimetry for Measuring Bidirectional Reflectance and Metabolites in Maize
Colleen J. Doherty
Project runs from 07/01/2020 to 06/30/2023
The purpose of this project is to develop a handheld Mueller matrix polarimeter that can be deployed to measure leaves in transmission. Leaves from different corn varieties will be quantified using both this handheld unit and our laboratory unit (an imaging Mueller Matrix polarimeter). These data will be compared to ground truth from e.g., enzymatic, colorimetric, 1D-NMR, and Mass-spectrometry based analyses, to correlate polarimetry measurements to metabolic concentration. Additionally, we will investigate polarization in reflection using a hyperspectral imaging polarimeter to quantify polarization’s ability to correct for bidirectional reflectance effects from canopy level measurements.
