Abstract
The group index, n
g
, group velocity dispersion (GVD), and
scattering attenuation coefficient, μ
s
, were measured for dilutions of
glycerol, ethanol, and Intralipid 20% with water. Experiments were
performed with a supercontinuum laser based Mach–Zehnder
spectroscopic interferometry setup for wavelengths between 400 and
930 nm. All optical properties could be retrieved from a single
calibrated measurement of the interference spectrum. Scattering
attenuation was determined from the envelope of the interference. The
group index and GVD were retrieved from the unwrapped spectral phase.
It was found that the group indices of glycerol and ethanol dilutions
are in accordance with the Lorentz–Lorenz mixing formula. The
scattering attenuation matches well to a semi-empirical model based on
the Twerksy effective packing fraction.
