Comparison of total reflection and transmission
Tables (4.1) and (4.2) compare
delta-Eddington values of total reflection and total transmission with the
exact values from Tables 3.3-3.6.
The first table assumes index matching
and the second assumes that the medium is bounded by glass slides to form a
air-glass-tissue-glass-air medium. For this case the indices of refraction
vary as 1.0/1.5/1.4/1.5/1.0 according to the layer in the
air-glass-tissue-glass-air medium. The errors for the index mismatched
case are roughly twice those of the index matched case. Both absolute
differences and relative errors are tabulated. This is because often when
the reflection or transmission is small, there is a relatively large
difference between the delta-Eddington and the exact values. However, the
difference is so small that for all practical purposes the difference
cannot be measured.
