Abstract

Here we present a methodology to characterize the light intensity fluctuations that arise from rotations of individual granular particles. We describe a setup for dynamic light scattering measurements on individual macroscopic particles and isolate the contribution from rotations of the individual particles to the obtained correlation functions. The results show that rotation of granular particles results in a significant contribution to scattered light intensity fluctuations, a phenomenon not considered so far in dynamic light scattering measurements on fluidized granular media. The results presented here may thus form the basis for an extended light scattering methodology for granular media, and improve the selection of granular particles according to their dynamic light scattering signal.
