Thermograms are records of density levels which correspond to apparent temperatures. The process of thermographic imaging is based on Plank's law which relates temperature to radiance. It begins with the collection of quantum energy which is then converted to voltage. The voltage powers a light source to expose the recording material of the thermogram. Atmospheric effects must also be taken into consideration. The relationship which takes all variables into account can be found in appendix A.
