Plant Thermal Imaging

Plant Thermal ImagingThe WPS Plant Thermal Imaging Module allows extracting information from the long-wavelength infrared (LWIR) range of the electromagnetic spectrum in the plants. The Infrared module is used to measure plant and leaf temperature in a non-destructive manner, which is indicative of plant water use behavior, including transpiration and leaf stomatal conductance.

Water taken up by the roots is lost at the level of the leaves by transpiration through stomata. Evaporation of this water results in cooling of the leaf surface. Upon drought stress response, plants close their stomata, resulting in an increased leaf temperature. High-performance industrial infrared cameras are implemented both in top view and side view configuration.
