Simple formulas for the volume absorption coefficient in asymptotic light fields
SIO Reference 58-79. It is now a well-established fact that the properties of the light field in optically deep homogeneous stratified media (such as deep cloud layers, oceans, lakes, etc) become extremely regular and predictable at great depths. The conceptual and practical consequences of this fact, however, are only in the first stages of exploration. In this note we derive some further consequences from this regularity.
