This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. An approach to the examination of the structure of layered biological tissue can be found in the measurement of the reflectance of plane diffuse photon density waves in the near-infrared range. The objective of this project is to take phase resolved reflectance measurements from both phantoms and biological tissues at moduolation frequencies of up to 2 GHz and to show the validity of the diffusion model to describe the measured phenomena. The technique allows the investigation of the structure of tissue to depths of 4-8 mm. A medical application may be found in improved examination techniques for deep burns as the method allows the investigation of the tissue structure without physical contact to the surface.

本子项目是利用由NIH/NCRR资助的中心赠款提供的资源的众多研究子项目之一。子项目和研究者（PI）可能已经从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。列出的机构是中心的，不一定是研究者的机构。在近红外范围内测量平面漫射光子密度波的反射率，可以找到一种检测层状生物组织结构的方法。该项目的目标是在高达2 GHz的调制频率下对幽灵和生物组织进行相位分辨反射率测量，并证明扩散模型描述测量现象的有效性。该技术允许对深度为4-8毫米的组织结构进行调查。在改进的深度烧伤检查技术中可以发现医学应用，因为该方法允许在不与表面物理接触的情况下调查组织结构。
