AB -  INSTRUMENT AND METHOD In the investigation two types of instruments were used - a thermal scanner, which in these studies used a wave-band of 8-14 micrometres and was mounted in a DC 3 aircraft, and an infrared television system with a wave-band of 2.0-5-4 micrometres. The two instruments thus make use of some of the most pronounced transmission windows in the atmosphere. The first-mentioned instrument was constructed and built at the Swedish Research Institute of National Defence. The last-mentioned instrument has been developed jointly by the AGA Company in Sweden and the Research Institute of National Defence, and has the registered trade mark AGA Thermovision. Both types of instruments scan the objects to be investigated and focus the infrared radiation on a detector. The airborne apparatus produces an infrared image of the scanned terrain on a photographic fl. The infrared im television converts the radiation signal from the objects into a TV-picture, which then can be recorded, for instance by means of a Polaroid camera. In both cases areas with the same radiation temperature can be connected on the infrared image by isotherms. The grey tones of the image are a measure of the received radiation effect within
