Thermal imaging principle

All objects with a temperature higher than absolute zero (-273.15°C, 0 K) will emit infrared radiation. The higher the temperature, the greater the radiation intensity. Thermal imaging usually uses the far infrared band of 8-14 microns. The infrared detector equipped with thermal imaging equipment can detect the intensity of infrared radiation of different wavelengths. Among them, the uncooled detector uses the thermoelectric effect or resistance change, which is usually used in portable thermal imaging equipment; the cooled detector requires a low-temperature working environment and has high sensitivity, which is suitable for high-precision scenes such as military and science.

The infrared detector converts the captured thermal radiation signal into an electronic signal. The intensity of the electronic signal is proportional to the temperature of the object. The electronic signal is digitized and the temperature data is mapped to different colors or grayscale values through a pseudo-color mapping algorithm, and finally a thermal map reflecting the temperature distribution of the object surface is generated.
