2. Infrared Thermography

Infrared thermography (IR) is a technique for determining quantitatively measurable characteristics (temperature) of live organisms. The premise that makes this method virtually universally applicable is that all objects generate IR radiation that is proportional to their temperature due to the movement of molecules, which causes charge displacement and thus electromagnetic radiation in the form of photons. Electromagnetic radiation can be deflected, focussed, or reflected from surfaces that can be utilized with thermo-electronic devices. The wavelength of this radiation ranges from 0.7 to 1000 meters. The IR radiation observed is converted into electrical impulses by IR thermography. Because the majority of infected sugarcane pests are found in the stem, thermal imaging can identify the temperature of the pest by locating the regions where the temperature is high, because the insect's respiration produces heat that is higher than the plant's.
