Abstract:
Dynamic light-scattering signals in the current detection mode are normally analyzed in the frequency domain. We propose an optimized inversion procedure for retrieval of the size distributions of the measured particles from such signals, including proper signal preprocessing and application of a Chahine-like relaxation technique, to solve a matrix equation. As for the results of the numerical experiments, the median value of the index of the discrepancy between the output distribution and the true one was mostly under 25% with 2% rms noise on the power spectral density of raw signals.
