A new microscopic principle based on radiometric stereo microscopy is presented, which is designed for investigating macro‐dispersion of filler in rubber. The image acquisition is combined with a stereological method of estimating the volume‐weighted size distribution of the filler particles. Experimental results for carbon black filler in rubber obtained by radiometric stereo microscopy are compared with those from microtomography using synchrotron radiation, and, furthermore, a simulation study is used for evaluation. It turns out that using the new three‐dimensional microscopic method, the size distribution of the filler particles can be estimated from fresh cuts of rubber with high accuracy, and thus it is an interesting alternative to well‐established dark field microscopy.

用辐射立体显微镜估计填料在橡胶基体中的宏观分散

提出了一种基于辐射立体显微镜的新微观原理，旨在研究填料在橡胶中的宏观分散。图像采集与估计填料颗粒体积加权尺寸分布的体视学方法相结合。将通过辐射立体显微镜获得的橡胶中炭黑填料的实验结果与使用同步辐射的显微断层扫描的结果进行比较，并进一步使用模拟研究进行评估。事实证明，使用新的三维显微方法，可以从橡胶的新鲜切割中高精度地估计填料颗粒的尺寸分布，因此它是完善的暗视野显微镜的有趣替代方案。
