Near-infrared spectroscopy and imaging using scattered light potentially evaluate the structural properties of the medium, like the average particle size, based on a relation between its structure and light scattering. A qualitative understanding of light scattering is crucial for developing optical imaging techniques. The scattering properties of dense colloidal suspensions have been extensively investigated using the electromagnetic theory (EMT). The colloidal suspensions are widely used in liquid tissue phantoms for optical imaging techniques and are encountered in various fields, such as the food and chemical industries. The interference between electric fields scattered by colloidal particles significantly influences the scattering properties, so-called the interference effects. Despite many efforts since the 1980s, a complete understanding of the interference effects has still not been achieved. The main reason is the complicated dependence of the interference on the optical wavelength, particle size, and so on. This paper briefly reviews numerical and theoretical studies of the interference effect based on the dependent scattering theory, one of the EMTs, and model equations.

使用散射光的近红外光谱和成像可以根据介质的结构和光散射之间的关系来评估介质的结构特性，例如平均粒径。对光散射的定性理解对于开发光学成像技术至关重要。使用电磁理论（EMT）广泛研究了致密胶体悬浮液的散射特性。胶体悬浮液广泛应用于光学成像技术的液体组织模型中，并应用于各个领域，例如食品和化学工业。胶体颗粒散射电场之间的干涉显着影响散射特性，即所谓的干涉效应。尽管自 20 世纪 80 年代以来进行了许多努力，但仍未实现对干扰效应的完整理解。主要原因是干涉对光波长、粒径等的复杂依赖性。本文简要回顾了基于相关散射理论（EMT 之一）和模型方程的干​​涉效应的数值和理论研究。
