Theory
The specific intensity
of light in a threedimensional infinite medium with a point source at
the origin obeys the following RTE.
where
Here we assume linear scattering and the scattering phase function is given by
The energy density U is obtained as
where v is the speed of light in the medium.
Since U is spherically symmetric, we measure U along the
zaxis.
We have
