8.2.4 Relationship between ARS, TS, ρ, and τ
By comparing Equations 8.1 and 8.2, it becomes obvious that TS
b
and TS
f
can be derived
from ARS by integration over the corresponding scattering hemispheres:

For a given sample irradiated with a certain incident power, the sum of all specular
and diuse components and the absorptance (A) should be equal to 1. is is usually
referred to as the energy balance:
