Thermal Imaging (TI) was originally developed for military use, the technology provided the ability to see and direct opposition forces at night or on the battlefield, covered with smoke. This is achieved by the fact that all objects have a temperature and emit energy waves, called infrared radiation, so hot objects produce more energy than cold objects. Thermal Imagers interpret these energy waves in the “thermal pattern,” the hotter images appear white, and the colder ones black. We can compare TI with the human eye, since they are both receivers, the eye receives "visible light", while the imager receives infrared radiation. Both the Imager and the human eye cannot see through most materials, but the Imager has the advantage of detecting different temperatures of structures, for example, “seeing” the pin behind drywall. Today, thermal imaging has expanded its use for fire, industrial, security, transportation, law enforcement and many other industries.
Equipped with firefighters, TI will no longer search each room to find an unconscious victim, in which case the victim will be depicted as black, while the fire will be white. Firefighters would also have the ability to detect hot spots inside the structure, identify a disoriented adult or child lost in the forest, or who was thrown out of a car accident. Line companies of the power company may detect faults before a power outage. Industries can solve engine problems to prevent overheating. Doctors and veterinarians use technology to measure the temperature in warm-blooded animals and people. Construction personnel have the opportunity to see heat leaks to increase the efficiency of heating and cooling. Boats, personal water crafts and swimmers contrast sharply with water or the coastline, making it easy to find them, even in nebula conditions, but one departure from TI is that he cannot see underwater objects or people. Hunters can use them to find their downed game. Home inspectors use them to detect flaws and possible hazardous areas. By scanning light switches and wall outlets, the imager can detect and prevent structural fire hazards in your home. They can provide personal safety from animals or human predators.
In these examples, we can conclude that Thermal Imaging technology has expanded significantly since 1994. These Imagers are now able to locate, locate, measure and provide security. It is no longer just military, but hunters, law enforcement agencies, firefighters, industrial enterprises, and even every day homeowners can and should benefit from thermal imagers.
