Kerr–Fourier imaging of hidden objects in thick turbid media

Abstract

Test bar charts hidden in a 5.5-cm-thick 2.5% Intralipid solution were imaged as a function of phantom depth and size with steady-state Fourier and picosecond Kerr–Fourier imaging systems. With time and space gating, a series of 250-μm bars placed in a thick highly scattering medium were resolved at a signal level of ~10−10 of the illumination intensity.
