通过在流变仪中安装小角光散射仪和光学显微镜，构造流变光学装置，以研究复杂液体（或软凝聚体）的流变性质与结构之间的关系。该装置的设计使我们能够同时测量稳态和动态剪切场下的流变特性、光散射和透射光学显微照片。它涵盖了广泛的扭矩范围：它适用于只有水的小粘度<1mPa的系统以及具有高剪切模量G′ <109 Pa的散装聚合物系统。 组装的透镜和冷却的电荷耦合器件相机允许我们定量测量的二维光散射图案。对于动态剪切场，光散射测量和光学显微镜观察都可以与文中定义的给定应变相φ同步。初步的实验表明，该装置是可行的。
A rheo-optical apparatus is constructed by installing a small-angle light scattering instrument and an optical microscope in a rheometer to investigate relationships between rheological properties and structures in complex liquids (or soft condensed matters). The apparatus is designed in such a way that it really enables us to measure simultaneously the rheological properties, light scattering, and transmission optical micrographs under both steady and dynamic shear field. It covers over a wide range of torque: it is applicable to systems having only the small viscosity of water ∼1 mPa as well as polymer systems in bulk having a high shear modulus G′∼109 Pa. An assembly of lens and a cooled charge coupled device camera allow us quantitative measurements of 2D light scattering patterns. For dynamic shear field, both light scattering measurements and optical microscopy observations can be synchronized with a given strain phase φ, defined in the text. Preliminary experiments with the apparatus are demonstrat...
