通过全息视频显微镜记录的胶体球全息图可以用光散射理论进行分析，以千分之一的分辨率测量单个球的尺寸和折射率。反过来，这些信息可以被解释为估计每个球体的孔隙度。
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.
