Schematic of a system for measurement and analysis of dynamic light scattering. (A) Rapid fluctuations of scattered light intensity are recorded at a resolution of ~ 1 μs. (B) The raw data are processed in firmware to yield the autocorrelation function given in text equation [7]. (C) The detailed shape of the autocorrelation function may be processed using various algorithms to yield an estimate of the intensity-weighted distribution of the size of equivalent spherical particles representing scattering species.
