光学相干层析成像（OCT）是一种非接触、非破坏性地对散射介质中的微结构进行成像的技术。OCT在高散射材料如聚合物复合材料中的应用尤其具有挑战性。在这项工作中，OCT作为一种技术来评估图像纤维丝束和两种材料中的空隙：环氧E-玻璃增强复合材料和乙烯基酯E-玻璃增强复合材料。使用OCT检测到的功能进行了比较与光学显微镜。玻璃纤维增强聚合物复合材料的纤维结构和空隙可以成功地使用OCT成像。OCT图像的质量受到纤维和增强材料之间的折射率失配的强烈影响。图像中最大的噪声源来自光纤透镜效应、样品内部的干扰以及表面处非常大的反射。(C)1998爱思唯尔科技有限公司版权所有。
Optical coherence tomography (OCT) is a nondestructive and noncontact technique to image microstructure within scattering media. The application of OCT to highly scattering materials such as polymer composites is especially challenging. In this work, OCT is evaluated as a technique to image fiber tows and voids in two materials: an epoxy E-glass-reinforced composite and a vinyl-ester E-glass-reinforced composite. Features detected using OCT are compared with optical microscopy. Fiber architecture and voids of glass-reinforced polymer composites can be successfully imaged using OCT. The quality of the OCT image is strongly affected by the refractive index mismatch between the fibers and reinforcement. The largest sources of noise in the images arise from fiber lens effects, interference from within the sample, and a very large reflection at the surface. (C) 1998 Elsevier Science Ltd.
