Abstract
This paper presents the problem of light scattering in particle sizing in a totally different approach than that developed in a previous work [1]. Basic mathematics is briefly exposed as well as the advantages and the drawbacks of this new algorithm in comparison with the preceding one. The results of the tests we carried out - including simulations and real data tests - emphasize the good resolution and numerical stability of this method. The algorithm substantially reduces the broadening effect of narrow dimensional distributions and small intensity maxima in more complex distributions are clearly distinguished. The important role of signal-to-noise ratio (S/N) in data acquisition is extensively discussed and argued.
