Principle of infrared thermal imaging

Infrared thermal imaging technology is a promising high-tech. The electromagnetic wave longer than 0.78 micrometer is located outside the red color of the visible spectrum. It is called infrared or infrared radiation. It refers to electromagnetic waves with a wavelength of 0.78~1000 microns. The part with a wavelength of 0.78~2.0 microns is called near-infrared and the wavelength is 2.0~1000. The part of the micrometer is called hot infrared. In nature, all objects can radiate infrared rays, so the infrared difference between the target itself and the background can be measured by a detector to obtain different infrared images of thermal infrared rays.
