在微米和纳米尺度上测量固体颗粒的形状、表面和聚集体结构对于产品和工艺的设计和表征变得更加重要。目前，这些性质是通过扫描电子显微镜或透射电子显微镜等成像技术离线确定的。这需要合适的取样，并且随后的后处理和分析步骤非常昂贵和耗时。因此，需要一种合适的测量技术，能够在线捕获这些特性。在这项工作中，一种新的传感器系统的基础上的原则，在气相中的颗粒的弹性光散射的开发和描述。在这里，气溶胶流的单个颗粒被单色激光照射，并且在颗粒周围的几个点处以高时间分辨率测量散射光强度。测量的数据进行评估，并用于获得某些颗粒特性，如尺寸，球形度和分形维数。传感器的模块化设置适合于适应不同的测量任务。除了详细描述所开发的系统的设计，第一次测量聚苯乙烯乳胶单球。
The measurement of the shape, surface, and aggregate structure of solid particles on the micro and nanoscale become even more important for the design and characterization of products and processes. Currently, these properties are determined offline via imaging techniques such as scanning electron microscope or transmission electron microscope. This requires a suitable sampling, and the subsequent workup and analysis step is very costly and time consuming. Therefore, a suitable measurement technology is required, which is able to capture the properties online. In this work, a novel sensor system based on the principle of elastic light scattering of particles in the gas phase is developed and described. Here, the single particles of an aerosol stream are illuminated by monochromatic laser light and the scattered light intensity is measured with high temporal resolution at several points around the particles. The measured data is evaluated and used to obtain certain particle properties such as size, sphericity, and fractal dimension. The modular setup of the sensor is suitable for the adaption to different measuring tasks. In addition to the detailed description of the design of the developed system, first measurements on polystyrene latex monospheres are presented.
