Multimodal hyperspectral, Raman and x-ray fluorescence imaging for pigment identification in heritage

该项目的目的是设计、建造、测试和使用一种用于遗产成像的高光谱、拉曼和X射线荧光扫描系统。该项目还需要开发定制的分析方法，将这些图像结合起来，并对其进行处理，以生成化学成分的图像。具体的探索途径可以包括：-对同一物体在不同系统上拍摄的图像进行排列和配准--确定文物的光学和X射线辐射的安全暴露限度--开发数学方法，通过生成文物保护者、历史学家、档案馆等感兴趣的衍生属性的图像(包括化学成分、酸度、聚合度、应力和应变)来告知文物的成分。-制定工作流程，有效地对ISH广泛参考资料收集和其他地方的真实历史样本进行成像。

The aim of this project is to design, build, test and use a combined hyperspectral, Raman and X-ray fluorescence scanning system for heritage imaging. The project will also require development of bespoke analysis methods for combining these images and processing them to generate images of chemical composition.Particular avenues of exploration could include:- Aligning and registering images taken of the same object on different systems- Determining safe exposure limits for optical and X-ray radiation on heritage objects- Developing mathematical methods to inform the object's composition by generating images of derived properties of interest to conservators, historians, archivists etc (including chemical composition, acidity, degree of polymerisation, stress and strain). - Developing workflows for effective imaging of real historical samples from ISH's extensive reference collection and elsewhere.
