为了准确测量混浊样品的相干反射曲线，我们构建了一套自动反射测量系统，并分析了镜面反射角附近相干反射和漫反射的存在。利用菲涅耳方程对相干反射曲线进行非线性回归，验证了一种确定混浊样品复折射率的现有方法。在325、442、532、633、850、1064、1310和1557 nm 8个波长测定了新鲜猪皮肤表皮、真皮组织和Intralipid溶液的复折射率。(C)2005年美国光学学会
We constructed an automated reflectometry system for accurate measurement of coherent reflectance curves of turbid samples and analyzed the presence of coherent and diffuse reflection near the specular reflection angle. An existing method has been validated to determine the complex refractive indices of turbid samples on the basis of nonlinear regression of the coherent reflectance curves by Fresnel's equations. The complex refractive indices of fresh porcine skin epidermis and dermis tissues and Intralipid solutions were determined at eight wavelengths: 325, 442, 532, 633, 850, 1064, 1310, and 1557 nm.
