FAST PARTICLE DETECTION METHOD AND SYSTEM ON BASIS OF DYNAMIC LIGHT SCATTERING SAMPLE ENSEMBLE ANALYSIS

摘要

A fast particle detection method and system on the basis of dynamic light scattering sample ensemble analysis. Firstly dispersing a particle sample to be detected so as to construct a plurality of sampling bodies, and collecting dynamic scattering optical signals in parallel; constructing a sample ensemble from the sample body scattering signals; analyzing and calculating the time relevance of the sample ensemble; and carrying out particle detection by means of particle motion characteristics. The time of measuring particles at a single instance may be several or dozens of milliseconds, so that real-time detection is facilitated; by combining the detected plurality of scattering signals which comprise amplitude and phase information, more accurate and reliable relevance representation may be obtained; and the method and system have a spatial resolution capability for particle detection, and the particle motion characteristics of spatial resolution may be determined.
