Description
Abstract: Thermography is a non-destructive evaluation tool to measure
the amount of infrared energy emitted by an object. This energy depends
on temperature and wavelength and is described by Planck's law. From the
solution of the wave equation the k-dependent photon energies and their
density of states are calculated. The equation of state and a statistical
description of the photon gas are presented. From the heat released during
condensation and the heat capacity as a function of temperature T the
dependence of the phase transition on the dimension d of the system is
discussed. It is shown that only the one and two dimensional gas show a
2nd order phase transition while in the 3d case a 1st order phase transition
is observed. Applications to real systems in nature are presented.
