Abstract

The acquisition of elemental and chemical distribution images on the surface of cultural heritage objects has provided us new insights into our past. The techniques commonly employed, such as macroscopic X-ray fluorescence imaging (MA-XRF), in general require pointwise or whisk-broom scanning of an object under constant measurement geometry for optimal results. Most scanners in this field use stacked linear motorized stages, which are a proven solution for 2D sample positioning. Instead of these serial systems, we propose the use of a parallel cable robot to position the measurement head relative to the object investigated. In this article, we illustrate the significance of the issue and present our own cable robot prototype and test its capabilities, but also discuss the current shortcomings of the concept. With this, we demonstrate the potential of cable robots as platforms for MA-XRF and similar imaging techniques.

缆索机器人作为传统线性平台的替代品,通过宏观 X 射线荧光成像技术研究形状复杂的物体
获取文物表面的元素和化学分布图像为我们了解历史提供了新的视角。常用的技术,如宏观 X 射线荧光成像(MA-XRF),一般需要在恒定的测量几何条件下对物体进行点扫描或拂扫式扫描,以获得最佳结果。该领域的大多数扫描仪都使用堆叠式线性电动平台,这是一种行之有效的二维样品定位解决方案。与这些串行系统相比,我们建议使用平行电缆机器人来定位与被测物体相对应的测量头。在这篇文章中,我们阐述了这一问题的重要性,并展示了我们自己的电缆机器人原型,测试了它的能力,同时也讨论了这一概念目前存在的不足。由此,我们证明了缆索机器人作为 MA-XRF 和类似成像技术平台的潜力。
