Self-adaptive adjustment of inverse range of dynamic light scattering particle sizing based on multi-scale transform

In dynamic light scattering particle sizing, the inverse range can be self-adapted closer to the true range by multi-scale transform. The simulative autocorrelation functions(ACFs) of unimodal size distribution particles of 200~600 nm and bimodal size distribution particles of 200~900 nm were inversed by the inverse range fixed and self-adaptive algorithms. Compared to the fixed algorithm, the selfadaptive algorithm is more precise and noise-tolerant. For unimodal distribution particles, it can reduce peak value error by 4.73% and peak width error by 185 nm at most. For bimodal distribution particles, when the noise level is 0～0.001, its peak value errors are less than by 11.33%,by 12.45%, and its peak width errors are less than 35 nm,160 nm. While, the fixed algorithm cannot get reason
