Imaging Polarimetry for Measuring Bidirectional Reflectance and Metabolites in Maize
This research will enable the development of new research techniques by NC State researchers.
This project seeks to develop a handheld Mueller Matrix Polarimeter that can measure leaves in transmission. Leaves from different corn varieties will be evaluated using both the handheld unit and a laboratory imaging Mueller Matrix Polarimeter. The data collected will be correlated to ground truth from various analyses, such as enzymatic, colorimetric, 1D-NMR, and Mass-spectrometry. Additionally, polarization in reflection will be investigated using a hyperspectral imaging polarimeter to quantify polarization's ability to correct for bidirectional reflectance effects from canopy level measurements. The outcome of this research will enable NC State researchers to develop new research techniques.

More Details
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.
