Thermal imaging is a non-contact method in which the radiation pattern of an object is converted into a visible image called thermal image or thermogram. All the objects at temperature above absolute zero (−273 °C) emit infrared radiation. The infrared band with wavelength from 3 to 14 µm is called thermal infrared region.

Second-generation infrared image sensors are becoming available in a variety of infrared detector materials, including photovoltaic HgCdTe, PtSi, and lnSb and photoconductive extrinsic silicon, PbS, and PbSe. We review the background of the evolution of infrared detector materials and summarize the formats and configurations available now in prototype ...

This chapter describes passive as well as active thermal methods and their applications in medicine. To keep the body temperature at a constant level, excess heat is released by evaporation, convection, conduction, and radiation. Evaporation of sweat is the most obvious mechanism.

The technology of CCD-type TV cameras combined with the technology of acoustically-tuned optical filters enables, for the first time, extremely sensitive and flexible infrared data acquisition combining both high spatial resolution and high spectral resolution. An instrument utilizing the above technologies is described and preliminary examples of data
