Infrared Radiation.
To produce thermogram it needs infrared wave. It is a radiant energy which cannot be seen by naked eyes and it was discovered by Sir William Herschel, an astronomer in the year 1800.
infrared waves
A thermogram is an image that shows regions of different temperatures in different colors. . A camera can take pictures of the infrared rays, and since some spots let of more infrared rays than others, you can get a detailed picture. Any objects with heat produce infrared rays.
I believe infrared detectors measure heat being given off by an object. However since everything gives off heat.. the detectors have to be cooled down to very low temperatures themselves using liquid helium croyogen. Emma D

It is called a Thermogram, or a Thermal Image

thermogram.
A thermogram is a device which measures heat through use of picture. The darker the colour, the cooler the object. White is the hottest point of the scale and Black is the coldest. A thermogram can be used in medicine - for brain scans and other explorative means. It can also be used to check insulation in buildings.
