This paper presents a combination of noninvasive techniques for the study of superimposed painting stages in The Pentecost, a Mexican Colonial panel painting attributed to Baltasar de Echave Orio (1558 - 1619). The application of reflected hyperspectral imaging (HSI) analysis for mapping the distribution of the pigments in the paint surface and the use of ultraviolet (UV) fluorescence photography and X-ray radiography as complementary imaging techniques provide new insights into the making process of the artwork, its manufacturing and conservation state. For a better understanding of the in situ results gathered, we studied a series of paint mock-up samples created following recipes and studio practices from art treatises. The use of spot analytical methods such as fiber optic reflectance spectroscopy (FORS) and X-ray fluorescence spectroscopy (XRF) allowed for a robust identification of the artist's materials.
本文提出了一种非侵入性技术的组合，用于研究归因于巴尔塔萨尔·德埃查韦·奥里奥（1558-1619 年）的墨西哥殖民时期的一幅《五旬节》镶嵌画的重叠绘画阶段。反射高光谱成像（HSI）分析在绘制颜料在绘画表面的分布方面的应用，以及紫外线（UV）荧光摄影和 X 射线照相术作为补充成像技术，为艺术品的制作过程、制作和保存状态提供了新的见解。为了更好地理解现场采集的结果，我们研究了一系列根据艺术论著中的配方和工作室实践制作的模拟画样本。使用光纤反射光谱（FORS）和 X 射线荧光光谱（XRF）等点状分析方法，可以对艺术家的材料进行强有力的识别。
