Photonic Imaging Strategies for Technical Art History and Conservation

项目简介：这是一个物理学博士研究项目。我们的物质文化遗产，无论是历史的还是当代的，都是由大量复杂的多层材料构成的。我们所看到的往往只是物体的表面和形状。下面隐藏着这些物品最初被创造出来的过程的材料和证据。通过使用最先进的成像/光谱系统来绘制构图并揭示它们的创作阶段，我们的目标是了解它们的意义和意义，无论是在它们的原始背景下，还是在我们今天。红外线成像和光谱学特别适合于观察表面以下，因为通常用可见光进行的散射通常要小得多。因此，红外线可以进一步渗透到物体中。根据材料及其结构的不同，红外线会吸收或反射回光线。通过利用Heriot-Watt开发的最先进的激光光源和提供大规模可调谐的红外光，我们将探索和开发几种新的成像技术，包括全场FTS、OCT和压缩光谱传感。

Project Description: This is a PhD research project in Physics. Our tangible cultural heritage, both historic and contemporary, is made from a plethora of complex multilayer materials. What we see is often only the surface and form of an object. Hidden below are the materials and evidence of the processes by which the objects were originally created. By using state of the art imaging / spectroscopy systems which can map the composition and reveal the stages of their creation, we aim to gain a understanding about the meaning and significance, both in in their original context and our present day. Infra-red imaging and spectroscopy is particularly suited of looking below the surface as the scattering which normally occurs with visible light is usually much less. Thus the infra-red penetrates further into the object. Depending on the material and its structure the infra-red light will absorb or reflect light back. By exploiting state-of-the-art laser sources developed at Heriot-Watt and providing massively tunable infrared light, we will explore and develop several techniques for novel imaging including full-field FTS, OCT and compressive spectra sensing.
