Abstract

A portable Mueller matrix imaging spectropolarimeter is presented, optimized for high throughput optical plant phenotyping, by combining a temporal and spatial modulation scheme. Critical aspects of the design included minimizing the measurement time while maximizing signal-to-noise ratio by mitigating systematic error for wavelengths spanning 405-730 nm. Validation results, which were taken in a redundant and non-redundant measurement configuration, indicated that the polarimeter provides an average absolute error of 5.3E-3 +/- 2.2E-3 and 7.2E-3 +/- 3.1E-3, respectively. Baseline polarization measurements are also provided of normal and barren Zea Maize hybrids (G90).
