...An error of 3% or less is considered acceptable.(30) Also, the method may be used to directly correct experimental ̄ndings obtained with the aid of integrating spheres....

...The term \adding" indicates that the doubling procedure may be extended to heterogeneous layers for modeling multilayer tissues or taking into account internal re°ections related to abrupt change in refractive index.(30) The adding-doubling technique is a numerical method for solving the 1D transport equation in slab geometry....

...In practice the two most common sources of experimental errors are (1) loss of light from the edges of the sample (which thereby invalidates the one-dimensional assumptions and underestimating both RT and TT) and (2) collecting scattered light in the unscattered transmission measurement (which thereby overestimates Tc)....
