Investigation of optical properties of scattering solutions by time-resolved transmittance

The optical properties of controlled size latex particles suspended in water have been investigated by using two different time-resolved transmittance set-ups. Least-mean square fitting between experimental data and analytical solution to diffusion approximation equation has given values of optical parameters in good agreement with the predictions of the Mie theory. In this way, the validity of these predictions was checked in the investigated experimental conditions and the data analysis confirms that time-resolved transmittance can be a reliable technique to measure the optical properties of scattering solutions.
