Particle measurement methods based on light scattering have the advantages of non-contact，wide measurement range and real-time measurement，etc.，and it is a principal method to measure physical and chemical properties of the particles.The main methods and principle that measure particle size，refractive index and concentration etc.based on light scattering are introduced，and application range of each method is also discussed.The research progress and aspects to be improved of particle measurement based on light scattering are described.Particle measurement methods based on light scattering focus on different aspects.The overall trend goes toward wider measurement range，higher accuracy and multiple-parameter measurement.
