In this work a method is proposed for estimating the PSD of a polymer latex from multiple angle dynamic light scattering (MDLS) measurements.  The problem consists in finding the PSD ordinates f(D) (with D particle diameter and f fraction by number) from the knowledge of the indirect measurements DDLS(q) (average particle diameter calculated from MDLS at each q)
