Modified iterative vector similarity measure for particle size analysis based on forward light scattering

摘要

The vector similarity measure (VSM), originally applied to information retrieval, has been recently introduced to analyze particle size distribution (PSD) based on forward light scattering. The VSM technique can predict the PSD with low sensitivity to the experimental errors. However, the simulations and experiments of multi-modal distributed particle systems were not satisfying. In this paper, a modified inverse algorithm is presented to improve the VSM technique. Simulated results and experimental evidence show that with this modification the VSM technique can reconstruct the PSD more efficiently. (C) 2016 Optical Society of America
