Abstract:
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.

Claim (Index 17):
The apparatus of the ultrafast particle dynamics measurement based on the photon ensemble correlation spectroscopy, as recited in  claim 15 , wherein:\n the optical illuminating and detecting device comprises elements selected from a group consisting of: an illuminating device using a plurality of light beams to illuminating different lateral space positions perpendicular to an optical axis direction, and a multi-detector device, for establishing the sampling volumes in a space dimension; an illuminating device using the light beams to illuminating a same space position or different space positions with different incidence angles, and the multi-detector, for establishing the sampling volumes in an angular dimension; a single-beam illuminating device formed by a plurality of sub-beams, wherein the sub-beams have different optical path delays and illuminate the same space position or the different space positions with the different incidence angles, so as to establish the sampling volumes in the angular dimension and detect the sampling volumes in parallel with optical path coding; and a multi-beam illuminating device with different spectrums, wherein different light beams illuminates the same space position or the different space positions; which is specifically formed by using a plurality of light sources of the different spectrums for illuminating, or segmenting a single spectrum after using a wide-spectrum light source for illuminating, or both, for establishing the sampling volumes in a spectral dimension.
