In nature, all objects radiate infrared rays, so using the detector to measure the infrared difference between the target itself and the background, different infrared images can be obtained, called thermal images. The thermal image of the same target is different from the visible light image. It is not the visible light image that the human eye can see, but the image of the temperature distribution on the surface of the target. In other words, it is the surface temperature distribution of the target that cannot be directly seen by the human eye, but becomes a thermal image that can be seen by the human eye to represent the surface temperature distribution of the target. Using this method, long-distance thermal image imaging and temperature measurement of the target can be achieved, and intelligent analysis and judgment can be performed.

In layman's terms, a thermal imager converts invisible infrared energy emitted by an object into a visible thermal image. The different colors on the top of the thermal image represent the different temperatures of the object being measured. By viewing the thermal image, you can observe the overall temperature distribution of the measured target, study the heating of the target, and then judge the next step. Modern thermal imaging cameras work by using optoelectronic devices to detect and measure radiation and create a correlation between radiation and surface temperature. The thermal imager uses the infrared detector and the optical imaging objective to receive the infrared radiation energy distribution pattern of the measured target and reflect it on the photosensitive element of the infrared detector to obtain an infrared thermal image, which is related to the thermal distribution field on the surface of the object.
