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.

该项目的目的是设计、建造、测试和使用一种组合的高光谱、拉曼和x射线荧光扫描系统，用于文物成像。该项目还需要开发定制的分析方法，用于组合这些图像并对其进行处理以生成化学成分图像。特定的探索途径可能包括：-在不同系统上对同一物体拍摄的图像进行对齐和注册-确定遗产物体的光学和x射线辐射的安全暴露限制-通过生成保护人员，历史学家，档案管理员等感兴趣的衍生属性图像（包括化学成分，酸度，聚合程度，应力和应变），开发数学方法来告知物体的组成。-开发工作流程，对ISH广泛的参考馆藏和其他地方的真实历史样本进行有效成像。
