Characteristics of the temporal point spread functions (TPSFs) of chaotic laser through intralipid solution are experimentally studied. Based on the delta function characteristic of the correlation function of chaotic signal, we retrieve TPSFs of the measured system with chaotic laser as light source by correlating the detected signal with the original signal. The scattering coefficient is increased by increasing the concentration of intralipid solution. While the absorption coefficient maintains unchanged, TPSFs of the intralipid solution at different concentrations are experimentally measured and the differential path-length factors (DPFs) are extracted from the TPSFs of intralipid solution, which can qualitatively reflect the optical properties of the intralipid solution. Results show that degree of the correlation between the two signals is decreasing with the increasing concentration of intralipid solution, and DPFs are positive correlation with the scattering coefficient of intralipid solution.
