We demonstrate that Fourier-domain transmission OCT is a versatile tool to measure optical material properties of turbid media. We develop an analytical expression for the transmission OCT signal. Based on this analysis we
determine the group refractive index, group velocity dispersion, absorption coecient, and scattering coecient. The optical dispersion is accurately measured for glasses, liquids, and water/glucose mixtures. The optical attenuation is measured in the spatial domain and compared to Mie calculations combined with concentration dependent scattering eects. In the wavevector domain the spectral dependence of the optical attenuation is measured and compared to literature values. The developed technique can be used for optical sensing of
attenuation and dispersion.
