Thermography has become an intensive domain of research. Initially it was introduced in military to be able to see threats in dark areas in early twenty century. In 1948 it took 40 minutes to scan a thermal image of a person. Since then technology has evolved rapidly. The vast range of its application makes the technology so appealing to the researchers. It is used as an inspection tool in industries as well as in major science discoveries. For lack of appropriate experimental results it is not yet considered to be a trusted tool in medical science. Major issue of this technology is its expensiveness. This paper mainly focuses on the applications of this technology, its effectiveness on the respective domains and some research, experiments and their results.
