摘要
An apparatus of ultrafast particle dynamics measurement based on photon ensemble correlation spectroscopy include steps of: dispersing a particle sample to be detected; establishing a plurality of sampling volumes, and collecting dynamic scattered light signals in parallel; and constructing sample ensembles based on scattered signals of the sampling volumes, analyzing time correlations between the sample ensembles, and detecting particle dynamic characteristics. A period for a single measurement of particles according to the method can be in the range of several milliseconds to several tens of milliseconds, which is conducive to real-time detection. More accurate and reliable correlation characterization can be obtained by combining the detected complex-valued scattered signals with both amplitude and phase information. Furthermore, the particle detection is able to be spatially resolved, so as to achieve spatially resolved particle dynamic characteristics.
