Diffusing wave spectroscopy (DWS), which makes use of multiple scattered light in concentrated and highly turbid colloidal systems, has emerged as a very reliable and promising technique to probe their dynamics and rheology. However, the application of DWS to the multiple emulsion systems, particularly double emulsions (DEs), has been relatively limited so far despite their significant potential in the diverse fields of applications including food, pharmaceuticals, and cosmetics. The potential of DSW could facilitate gaining a more detailed understanding and quantitative measurement of the factors that govern the dynamics, structure, and properties of DEs, and most importantly their stability. This review briefly describes fundamental principles of DWS and its potential application to DEs to study the evolution of dynamics and structure at various time and length scales, as well as the rheological properties.

在集中和高度混浊的胶体系统中利用多重散射光的扩散波谱（DWS）已经成为一种非常可靠且很有前途的技术，可用来探测其动力学和流变学特性。然而，迄今为止，DWS在多种乳液体系中，特别是在双乳液（DEs）中的应用相对有限，尽管它们在包括食品，药品和化妆品在内的各种应用领域中具有巨大潜力。DSW的潜力可​​以促进对支配DE的动力学，结构和特性以及最重要的是其稳定性的因素进行更详细的了解和定量测量。
