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.

项目描述：这是一个物理学博士研究项目。我们的有形文化遗产，无论是历史上的还是当代的，都是由大量复杂的多层材料构成的。我们看到的往往只是物体的表面和形式。下面隐藏的是这些物品最初创造过程的材料和证据。通过使用最先进的成像/光谱系统，可以绘制成分并揭示其创作阶段，我们的目标是了解其原始背景和当今的意义和重要性。红外成像和光谱学特别适合于观察物体表面以下的情况，因为通常可见光发生的散射通常要小得多。因此红外线可以更深入地穿透物体。根据材料及其结构，红外光将吸收或反射光。通过利用Heriot-Watt开发的最先进的激光源并提供大量可调谐红外光，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。
