Abstract
A coupled integrating sphere system was used to measure the diffuse reflectance and transmission of rabbit aortae. Tissue absorption coefficients and scattering coefficients were calculated by a Kubelka-Munk model, and the results were compared. The absorption coefficient in (Beta) -carotene stained plaque was found to be greater than that in normal controls by fourfold at 488 nm wavelength, and by threefold at 514 nm wavelength. The scattering coefficient, however, did not change significantly between (Beta) -carotene stained and non-stained rabbit aortae.
