| Summary: | 碩士 === 國立成功大學 === 光電科學與工程學系 === 104 === In this thesis, we demonstrate the use of optical method, diffuse reflectance spectroscpoy (DRS), and we will the obtain spectrum of liquid phantoms from DRS, to investigate physiological parameters of liquid phantoms. First, we will obtain reflectance of phantoms at the range of 500nm to 1000nm. Further we will compare two spectral fitting methods of DRS in measuring biological optical properties, one is Multi-Wavelength method and another is Multi-Distance method. The liquid phantoms are used to measure the absorption and scattering coefficient under the range of normal and tumorous breast tissue by these two spectral fitting methods, and to compare both effect. The purpose is to construct a non-invasive, cheaper and simple optical system, and the system can quantify the chromophore concentrations of breast tissue in the future.
