1. Infrared radiation sources
1.1 Radiation emission
Thermal emission from matter is one form of light-matter interaction. Using "Einstein coefficients" reasoning on a simple two-level system, E 1 and E 2 at temperature T, in the presence of a set of photons whose spectral volume energy distribution is characterized by Φ eq (ν 12 ,T) at frequency ν = ν 12 (figure 1 a), we can place thermal emission in a framework common to three kinds of interaction: absorption,...
