uses of infrared radiationUsed in night vision devices to observe animals or people using the phenomenon called infrared illumination. The observant will not know that they are being observed.Used in astronomy to observe objects that are blurred and hidden by the interstellar dust. Infrared imaging process is used here.Used in astronomical telescopes that are equipped with infrared sensors and these telescopes are used to detect distant planets that are in the dusty regions of space, as they cannot be viewed using a normal telescope. They are also used to detect objects that have had a high red-shift (shifting of wavelength towards the red end of the spectrum).Used in infrared lamps (lamps that emit infrared radiation) and these lamps are used for drying paint, wallpapers and printing inks, to keep food warm, in heaters that are used during cold weather and in heat treatments in the field of medicineUsed in infrared lasers that produce infrared beams that can be used to read information on compact discs.Used in Infrared imaging devices that are used to obtain images of infrared radiation that are reflected or produced by objects, for example, heat insulation in buildings, sources of thermal pollution, mapping vegetation on the earth’s surface.Used in the chemical industry to determine molecular structure and composition of substances by studying their infrared emission or absorption.
