INVESTIGATION OF THE TEMPORAL SPREAD OF AN ULTRASHORT LIGHT-PULSE ON TRANSMISSION THROUGH A HIGHLY SCATTERING MEDIUM

An experimental and theoretical investigation of the temporal spread o f an ultrashort light pulse on transmission through a highly scatterin g medium has been made. For the strongly diffuse light, the transmitte d pulse may be described by a universal function whose duration can be directly related to the width of the sample. For sufficiently scatter ing samples, experimental data and the diffusion approximation indicat e that the output pulse duration scales with the square root of the sa mple width.
