Abstract :
The determination of particle size distribution (PSD) deals with ill-posed problems in dynamic light scattering (DLS) technique and small perturbation in measured data will cause serious errors in recovered PSD. In this paper, we proposed a modified technique which solves the second order correlation function directly. Simulated results show that this technique significantly reduced the inversion errors.
