Abstract
The temporal profiles of ultrashort light pulses propagating through t urbid media of different lengths were measured with a streak camera. V arious Fourier spatial filters were used to select the spatial frequen cies of the scattered pulses. The temporal profiles of the pulses scat tered by a 0.4% Intralipid solution in a cell of 5-cm thickness were s ignificantly narrowed because of the removal of the higher-frequency c omponents by a Fourier spatial filter.
