The principle of infrared thermal imager: different colors on the thermal image represent different temperatures of the object being measured. By looking at the thermal image, we can observe the overall temperature distribution of the measured target, study the temperature of the target, and then judge the next step. The working principle of modern thermal imaging cameras is to detect and measure radiation using optoelectronic devices to establish the relationship between radiation and surface temperature.
All objects emit infrared radiation above absolute zero (-273 degrees Celsius). The thermal imager uses an infrared detector and an optical imaging objective lens to receive the reflected infrared radiation energy distribution map of the target to be measured, and reflects it on the photosensitive element of the infrared detector to obtain an infrared thermal image. It corresponds to the heat distribution field on the surface of the object.
