Core principle of a laser particle size analyzer

Core principle of a laser particle size analyzer: A laser particle size analyzer determines the particle size distribution by measuring the light scattered or diffracted by particles. When a laser beam illuminates a group of particles, particles of different sizes produce scattered light at specific angles. These signals are captured by a multi-detector array and calculated using Mie scattering theory or Fraunhofer diffraction approximation algorithms, ultimately obtaining the size and distribution of the particles.
