INFRA-RED AERIAL THERMOGRAPHS

TERMOGRAMAS AEREOS INFRARROJOS

When the temperature of a body goes below absolute zero, the body emits infra-red radiation. The intensity of this electromagnetic radiation depends for the greater part on the temperature of the body. Therefore, a system able to graphically record variations in energy can supply extremely accurate temperature measurements. Details are given of A method of obtaining infrared thermographs; it consists in transforming the variations in radiation energy emitted by bodies into variations in electrical voltage by means of A sensor. By applying this technique to the surface of A terrain from an aircraft it is possible to obtain very useful information on the characteristics of this terrain, particularly in the detection of ground water. /TRRL/
