Interaction of light with tissues: A hyper-spectral approach

点击翻译按钮获取中文摘要

This project aims to address an important problem of noncontact assessment of tissue including skin and cartilage. By using extremely wide spectrum – between the terahertz and the near infrared – the effects of scattering and absorption arising from the variation of tissue properties from macro- to nano-scale will be explored. Spatial variations of tissue properties will be addressed in model and experiment by combining spectroscopy with the novel terahertz and mid-infrared Scanning Near field Optical Microscopy. The outcomes will advance fundamental understanding of light interaction with multi-layered tissues. This will provide a tool for advancing bioengineering research, terahertz technology, and development in biomedical devices.
