Abstract

The invention provides a particle size measurement method, device and equipment based on scattered light polarization detection. The method comprises the following steps of: acquiring two polarization images of a light path system collected by an image collector; performing operation on the two polarization images to generate particle images in the polarization images; according to the particle images, acquiring scattering polarization ratios of the light path system under different incident wavelengths and different observation angles; and performing inversion operation on the particles according to the scattering polarization ratios so as to obtain the overall optimal solution of the particles. The scattering polarization ratios are obtained based on image processing, the high requirement of absolute quantity measurement on a light path is avoided, and the experiment anti-interference performance is improved; and meanwhile, rapid online measurement can be realized.

Description

technical field [0001] The invention relates to the field of particle detection, in particular to a particle size measurement method, device and equipment based on scattered light polarization detection. Background technique [0002] Particle detection is a technology involving multiple disciplines and fields, mainly involving the acquisition of particle characteristics such as particle size, concentration and flow field. The real-time on-line detection technology of solid particles, liquid droplets, bubbles and other particles has been widely used in the fields of chemical industry, medicine, environmental protection, power and atmosphere. energy consumption etc. are important. [0003] In the existing particle size measurement technology, the optical scattering method has its irreplaceable advantages, because it can realize fast real-time measurement without interference and is easy to combine with other measurement methods to achieve simultaneous acquisition of two or mo...
