Abstract

A tunable thermal-infrared carbon-dioxide laser reflectance sensor operating in the 9-11 micrometer region of electromagnetic spectrum is being used to study plant physiological changes due to stresses. The system is capable of gathering information at various wavelengths, incident angles, and linear polarization combinations. Preliminary reflectance measurements of two different plant types demonstrate the possible potential of this system to characterize physiological changes due to induced freezing, chilling, and heat stresses.
