With support from the Chemical Measurement and Imaging Program and co-funding from the Office of International Science and Engineering, Prof. Murray Loew of George Washington University and Drs. John Delaney and Suzanne Lomax at the National Gallery of Art are undertaking studies aimed at developing in situ methods capable of comprehensive examination of entire artworks, providing images, or media maps, of the pigments used, which in turn provide insight into the artistic working method. Specifically, the team is constructing an infrared imaging spectrometer capable of standing off from and scanning an entire painting, with high spatial and spectral resolution. The scans will be analyzed to provide maps of the composition of the binding materials used in the paints. That knowledge will help historians to better understand, and conservators to better restore, important works of art. It will help art conservators and historians understand how evolutionary changes can influence an artist's painting technique and style. It will clarify how painters worked to alter the appearance of painted surfaces by experimenting more with the binders than with the pigments alone. Finally, for the conservator, finding regions of common binders is important for determining treatment approaches. The new instrument is likely to have utility beyond the field of art conservation; there are challenging material-identification problems in both biomedical imaging and homeland defense to which the standoff, high-sensitivity, high-resolution capabilities would be directly applicable. The work will provide hands-on experience to graduate and postdoctoral students by making clear the value of analytic techniques from chemistry and engineering in art conservation. Students will join collaborators in Perugia, Italy, for several months, learning their approaches to the issues and conducting some of the benchmarking, calibration, and new-sample-library studies. That exposure should be invaluable because it will make clear the similarities and differences of various points of view that are present in this interface, and force the students to examine problems from multiple directions. There also will be benefit from cross-cultural exposure and understanding. Results will be disseminated broadly, such as by publication in scientific and popular journals and by Web sites and exhibits at both George Washington University and the National Gallery of Art.

在化学测量和成像计划的支持下，以及国际科学与工程办公室的共同资助下，华盛顿大学的乔治教授默里·勒夫和国家艺术馆的约翰·德莱尼博士和苏珊娜·洛马克斯博士正在进行研究，旨在开发能够全面检查整个艺术品的原位方法，提供所用颜料的图像或媒体地图，这反过来又提供了对艺术工作方法的洞察。 具体来说，该团队正在建造一个红外成像光谱仪，能够远离并扫描整幅画，具有高空间和光谱分辨率。 将对扫描进行分析，以提供油漆中使用的粘合材料的成分图。这些知识将有助于历史学家更好地理解重要的艺术作品，也有助于艺术品保护者更好地修复重要的艺术作品，有助于艺术品保护者和历史学家了解进化的变化如何影响艺术家的绘画技巧和风格。 它将阐明画家如何通过更多地使用粘合剂而不是单独使用颜料来改变绘画表面的外观。 最后，对于保存者来说，找到共同的粘合剂区域对于确定治疗方法很重要。新仪器很可能具有超出艺术保护领域的实用性;在生物医学成像和国土防御中存在具有挑战性的材料识别问题，其中远距离，高灵敏度，高分辨率的能力将直接适用。 这项工作将通过明确化学和工程分析技术在艺术保护中的价值，为研究生和博士后学生提供实践经验。 学生将在意大利佩鲁贾与合作者一起工作数月，学习他们解决问题的方法，并进行一些基准测试、校准和新样本库研究。 这种接触应该是非常宝贵的，因为它将明确存在于这个界面中的各种观点的相似性和差异性，并迫使学生从多个方向检查问题。 跨文化的接触和理解也会受益。 研究结果将广泛传播，例如在科学和大众刊物上发表，并通过网址和在乔治华盛顿大学和国家艺术馆举办展览。
