PRINCIPLES AND APPLICATIONS OF INFRARED THERMAL IMAGING

Nowadays, due to the increasing spread of the coronavirus which effects the human temperature, there is a need for a framework useful for identifying temperature without any interaction with the human body. To measure the temperature in the human body in a noncontact way, infrared imaging technology can be used for the measurement of the body temperature quickly and effectively. The thermal imaging is a noncontact way of measuring the temperature which uses infrared radiation as a temperature-dependent parameter. Using thermal imaging, humans and other homothetic animals become visible even in day or night, so it is helpful for the military applications as well. A review of the other various applications of the infrared thermal imaging and the fundamentals of thermal imaging has been discussed in this paper. The further useful application of thermal cameras for COVID-19 is also analyzed.
