Abstract

Investigations on the propagation of light in random media have been of current interest The static backscattered light exhibits the photon localization (intensity enhancement) at the exact backward direction¹⁾. The dynamic backscattered light shows the minimum correlation time at the exact backward direction and double peaks in its both sides²⁾. Both features are closely related with each other by considering the trajectory of the photon transport in the media. In this study, we shall examine to derive the pathlength distribution function from the autocorrelation function using Levenberg-Marquardt method³⁾ and reveal the relation between the spatial and temporal features of the backscattered light from dense random media by using the pathlength distribution function.
