Abstract

We comment on the recent Letter by Calhoun et al. [Opt. Lett. 35, 1224 (2010)]. We wish to correct their statement about the order of the magnitude of the absorption coefficient of inks that we have we studied. In addition, we consider the inconsistency of their theoretical model with the experimental data obtained for milk and milk-cream samples.
