Abstract

Simultaneous measurements of particle sizes and number densities by means of the visible infrared double extinction technique are carried out and accurately validated. Accurate validation has been made possible by using a new kind of standard media, i.e., embedding the particles under study in a high viscosity gel. A byproduct of the work is a discussion of Beer-Lambert law limitations for multiple scattering in densely laden media.
