| Abstract: | Based on the principle of digital correlation, a digital correlator used for the measurement of dynamic light scattering was developed via the high-speed data acquisition card and the Laboratory of Virtual Instrument Engineering Workbench (LabVIEW). The experimental data were processed with this digital correlator and the autocorrelation function curves of light intensity scattered were presented. A better test result is concluded by comparing the recovered particle size and the known size. |
