Experiments to measure pulse stretching, delay, and attenuation of optical pulses due to multiple scattering have been performed on systems which are in effect scale model clouds. The scattering systems consist of emulsions of dielectric liquids dispersed in water. The dispersed liquid phase forms spherical droplets whose size and number density can be controlled by the preparation technique. The systems are stable over periods of several days when maintained in a rotating cylindrical scattering cell to reduce flocculation and prevent creaming.
