CStoDConverter
software to convert from particle scattering cross section to diameter
CStoDConverter uses scattering data to convert a particle's scattering cross section to a diameter. This is usually non-trivial because scattering cross section is a nonlinear and non-monotonic function of diameter. The software is targetted at performing refractive index corrections for optical particle counters. The scattering data used can be generated from Mie theory (the MieConScat software at http://sourceforge.net/projects/mieconscat can do this) or can be from any other source e.g. experimental data, your own Mie code, T-matrix calculations or any other scattering theory. ... -
