Normalized Chahine algorithm was used to alleviate spikes of the particle size distributions (PSDs) derived by truncated singular value decomposition (TSVD) method in dynamic light scattering (DLS) measurements and to enhance the validity for determining the optimal regularization parameter in the L-curve of TSVD method. Simulated results indicated that relative errors of recovered PSDs decreased after modification by normalized Chahine algorithm. The experiments also verified the results.
