遠離平衡態下軟物質結構形成與其時間依賴動態學的相關領域中,小角度光散射技術扮演至關重要的角色。世界上現行的實驗系統皆是研究單位自行設計與架設,而目前發表的研究成果又因儀器設計的精度而異。本文介紹近幾年來光散射技術的重要發展,尤其在如何將小角度光散射技術擴展到時間解析的動態學相關研究上。
Small-angle light scattering (SALS) is a useful technique to study the structural formation of jammed soft matters which are far from equilibrium. In this article, we review theory, instrument design, and applications of time-resolved dynamics and diffusing wave spectroscopy, which is believed to be one of the most important recent developed small-angle light scattering techniques.
