The thermal imager uses an infrared detector and an optical imaging objective to receive the infrared radiation energy distribution of the measured object and reflect it to the photosensitive element of the infrared detector, so as to obtain an infrared thermal image corresponding to the thermal distribution field on the surface of the object. Generally speaking, a thermal imager converts the invisible infrared energy emitted by an object into a visible thermal image. Different colors on the thermal image represent different temperatures of the measured object. The thermal imager has the advantages of being unaffected by visible light, clear imaging for 24 hours, non-contact temperature measurement, and smoke and fog permeability.

The application space of thermal imager is very wide, and it can be used in all aspects of life, such as epidemic prevention and control, human body temperature measurement, industrial temperature measurement (electric power detection, building detection, dangerous chemicals detection, household water, electricity and heating detection, etc. ), autonomous driving, outdoor observation and so on. I believe that in the near future, thermal imaging technology can be more fully popularized and applied.
