Using the principle of infrared imaging, an infrared imaging life detector can be made to search for survivors in ruins and rubble. The body temperature of the survivors can be found with a thermal imager. Using the principle of infrared imaging, by detecting the difference between the injured or the victim and the surrounding temperature and heat, an infrared image of the human body is formed, which helps the rescue team locate the position of the victim in or around the ruined area. Infrared imaging detectors can detect and display the body heat of victims, helping rescuers quickly locate victims buried under rubble or hidden behind dust clouds.
