摘要

Multiple light scattering can be suppressed by slightly tilting two single-mode fibers viewing the same sample volume. The cross-correlation function of the two signals shows more or less contributions from single scattering, depending on the tilt angle. We show experimental results for polystyrene spheres at a scattering angle of 90 degrees. The measured size, intercept, and second cumulant for different tilt angles demonstrate the practicality of this technique. Both polarization components show multiple-scattering contributions, but only the parallel component contains single scattering. (C) 1997 Optical Society of America.
