Method and apparatus of dynamic light scattering.

摘要

A method of dynamic light scattering, comprising the following steps: - illuminating a scattering volume fluid (SV) with coherent radiation temporally and spatially (B) in a plurality of discrete wavelengths, - detecting a fluctuation intensity of radiation scattered by scattering centers contained in said volume of fluid dispersion (SV) for each of said plurality of discrete wavelengths and - determining a property of said scattering volume fluid from said fluctuation detected the intensity of radiation in that it further comprises the following steps: - defining said intensity fluctuation of radiation at an angle of constant predetermined detection for each of said wavelengths wherein: - said step of determining a property comprises the step of determining a plurality of equivalent scattering angles related dedispersión with these centers from said detected intensity fluctuation of radiation of said plurality of discrete wavelengths.
