Goal of this work is to develop quantitative measurements in scattering media for both high and low concentration constituents. One aim of the program will provide a better basic understanding of the interaction of scattering in spectroscopic measurements. Quantification of constituents in scattering sample by optical measurement is limited by knowledge of the optical path in the sample. We propose to use a ultrasonically modulated optical approach to gain a knowledge of the scattering properties of a sample and thereby, improve quantification of optically absorbing constituents. The basic information gained in this work will provide approaches useful in fields ranging from biofluid analysis to pharmacueticals and paint manufacturing.

本工作的目的是在散射介质中对高浓度和低浓度成分进行定量测量。该计划的一个目的是为光谱测量中散射的相互作用提供更好的基本理解。通过光学测量来定量散射样品中的成分受到样品光路知识的限制。我们建议使用超声调制光学方法来获得样品散射特性的知识，从而提高光吸收成分的量化。在这项工作中获得的基本信息将为从生物流体分析到制药和油漆制造等领域提供有用的方法。
