Abstract
The intensity autocorrelation function of light through a dense intralipid suspension in the presence of an absorber was investigated by the photon correlation method. Then, we demonstrated that the parameter of the scattering can be obtained through the absorption effect with the diffusing-wave spectroscopy: diffusing-wave absorption spectroscopy. Firstly, the relation of the Laplace transform between the autocorrelation and path distribution functions was confirmed by using the time-of-flight method. Then, the linear shifts along the time axis of the autocorrelation function due to the absorption were also validated and the transport mean free path was obtained. Furthermore, this was also estimated from the intensity change by absorption.
