Thermal imaging camera and its working

  A Thermal Imaging Camera can capture and create an image of a particular object by using infrared radiation emitted from the object's surface in a process that is called thermal imaging or thermal screening. The created image represents the temperature of the respective object or individual. The underlying technology of the thermal imaging cameras was first developed for the use of the military. However, the invention of the thermal imaging camera is related to the history of thermography which began in the year 1960 by Sir William Herschel an astronaut who also discovered infrared light.  Both infrared radiation and visible light are an important part of the electromagnetic spectrum, but unlike visible light, Infrared radiation cannot be perceived with naked human eyes directly. This gives a major explanation that why a thermal camera system is not affected by the light to a greater extent and can provide us with a clear picture and temperature of an object or individual even
