A Thermographic camera is one of the most important devices that use infrared radiation to create an image. Infrared energy is just one part of the electromagnetic spectrum, which encompasses radiation from gamma rays, x-rays, ultraviolet, a thin region of visible light, infrared, terahertz waves, microwaves, and radio waves. These are all related and differentiated in the length of their wavelength. All objects emit a certain amount of black body radiation as a function of their temperature. Let's know more about the Thermographic camera in Electronics Engineering.
