Abstract

Holograms of colloidal spheres recorded through holographic video microscopy can be analyzed with the theory of light scattering to measure individual spheres' sizes and refractive indexes with part-per-thousand resolution. This information, in turn, can be interpreted to estimate each sphere's porosity.
