标题： COLIS: an advanced light scattering apparatus for investigating the structure and dynamics of soft matter onboard the International Space Station

摘要： 胶体固体（COLIS）是一种先进的光散射装置，专为国际空间站（ISS）上的实验而开发。 COLIS能够在从几纳米到几十微米的长度尺度以及从100纳秒到几十小时的时间尺度上探测软物质系统的结构和动力学。 除了传统的静态和动态光散射外，COLIS还包括去极化动态光散射、小角度相机、光子相关成像以及通过辅助近红外激光束对热敏感样品进行光学操控，从而为探测软物质系统提供了一个独特的平台。 我们通过在地面测试标准布朗悬浮液，以及与未来ISS实验中将使用的蛋白质、胶体玻璃和凝胶系统类似的系统来展示COLIS。 显示英文摘要

摘要： Colloidal Solids (COLIS) is a state-of-the-art light scattering setup developed for experiments onboard the International Space Station (ISS). COLIS allows for probing the structure and dynamics of soft matter systems on a wide range of length scales, from a few nm to tens of microns, and on time scales from 100 ns to tens of hours. In addition to conventional static and dynamic light scattering, COLIS includes depolarized dynamic light scattering, a small-angle camera, photon correlation imaging, and optical manipulation of thermosensitive samples through an auxiliary near-infrared laser beam, thereby providing a unique platform for probing soft matter systems. We demonstrate COLIS through ground tests on standard Brownian suspensions, and on protein, colloidal glasses, and gel systems similar to those to be used in future ISS experiments.
