Based on optical-path-length spectroscopy, we present a method for determining optical diffusion coefficients that does not require a priori knowledge about the physical properties of inherent interfaces. Comparisons are made with both standard theoretical estimates for bulk diffusion and with traditional approaches relying on surface corrections.
