Abstract
Recent activity has been directed toward the utilization of single-mode optical fibers in dynamic light scattering experiments.1,2 Single-mode optical fibers offer several advantages over conventional bulk optic light scattering arrangements, including miniaturization, remote detection, immunity from electromagnetic interference, in situ measurement capability, and suitability for turbid media. Also, single-mode fibers do not exhibit the modal noise encountered in light scattering arrangements utilizing multimode fibers. Presented here are particle size measurements based on the Brownian-induced phase noise in light scattered by a fluid suspension of polystyrene spheres.
