| Abstract: | Based on the analysis about photon correlation spectroscopy,a high time resolution experimental method for the measurement of dynamic light scattering is proposed.The dynamic light scattering experimental system is composed of a photomultiplier tube,a virtual digital store oscilloscope module and a personal computer.This experimental system is designed to work mainly on analog detection,in which the photomultiplier output is used directly as an analog signal.The test results of nanoparticles demonstrate that the time resolution of this experimental system is 12.5 ns. |
