Paper Abstract

The lower limit of size measurement with PDA is about 150nm particle diameter, because of the small scattering efficiencies under this size. A model-based signal processing method is developed to determine the particle size from the autocorrelation function constructed in photon counting LDA systems by simulating the whole scattering and detecting process. An optimization algorithm is proposed to fit the computed autocorrelation function to the measured one. The errors of this signal processing method are discussed.
