We report the recovery of broadband ( 650 1000   nm ) diffuse optical absorption and reduced scattering spectra stratified by layer in a two-layer phantom. The broadband optical properties of the phantom featured top and bottom layers designed to simulate adipose and muscle, respectively. The absolute value and dynamic variation of chromophore concentrations in both layers (top layer thickness greater than 5   mm ) were calculated with an average 10% error and 3% error, respectively. In addition to spectra, the algorithm recovers the top layer thickness up to 12   mm within 10% error. It is insensitive to initial guesses of both layers' optical properties as long as the layer thickness initial guess is within ± 2   mm .
