Abstract

The total rate at which energy is radiated by a source is the flux Φ measured in watts. Figure 2.1 shows a small area dA1 emitting radiation into the element of solid angle dΩ at the angle θ1 to the normal n1. The flux contained within this solid angle is simply proportional to the projected area dA1cosθ1 and dΩ, i.e.
$${\rm{d}}\Phi {\rm{ = }}I\,{\rm{d}}{A_1}\,\cos {\theta _1}\,{\rm{d}}\Omega $$
(2.1)
where the constant I is the photometric intensity of the source with dimensions of power per unit area per unit solid angle (Wm−2 ster−1). In the radiative transfer literature it is common to refer to this merely as the intensity and this convention will be adopted in this chapter. However, I must be distinguished from /used in Chapter 1, which is used for scattered intensity and has the dimensions of power per unit area (Wm−2).
