title: Simple and accurate expressions for diffuse reflectance of semi-infinite and two-layer absorbing and scattering media: erratum.
abstract: A previous paper [Appl. Opt.48, 6670 (2009)] presented analytical expressions for the diffuse reflectance of semi-infinite homogeneous and two-layer refracting, absorbing, and anisotropically scattering media exposed to normal and collimated light. It also reported various regression coefficients associated with the analytical expressions obtained by fitting the diffuse reflectance predicted from Monte Carlo (MC) simulations. Although the formulation and the MC simulation results were correct, the values of some regression coefficients were erroneously reported. This erratum points out the error in the original paper and reports the correct values. It also presents alternative expressions for when the medium has an index of refraction of 1.44, corresponding to the human skin in the visible portion of the spectrum.
