SYSTEM AND METHOD FOR REAL-TIME DETERMINATION OF PARTICLE SIZE DISTRIBUTIONS IN DRY POWDERS
Abstract: a method of monitoring a particle size distribution (psd) is provided. a plurality of particles having a particle size distribution (psd) may be illuminated by an at least partially coherent beam to produce scattered light. the scattered light may be captured by a pixelated photoelectric detector, thereby creating an ensemble of raw speckled images. based on the ensemble of the raw speckled images. an ensemble-averaged intensity correlation may be computed. the ensemble-averaged intensity correlation may be provided to an inverse module. the inverse module may be configured to determine the psd based on the ensemble-averaged intensity correlation. the particle size distribution may be obtained from the inverse module.
