Optical methods for monitoring physiological tissue state are important and useful because they are non-invasive and sensitive. Experimental measurements of the full scattering profile of circular phantoms are presented. We report, for the first time, an experimental observation of a typical reflected light intensity behavior for a circular structure characterized by the isobaric point. We previously suggested a new theoretically method for measuring the full scattering profile, which is the angular distribution of light intensity, of cylindrical tissues. In this work we present that the experimental result match the simulation results. We show the isobaric point at 105° for a cylindrical phantom with a 7mm diameter, while for a 16mm diameter phantom the isobaric point is at 125°. Furthermore, the experimental work present a new crossover point of the full scattering profiles of subjects with different diameters of the cylindrical tissues.
用于监测生理组织状态的光学方法非常重要且实用,因为它们是非侵入性的且灵敏。本文展示了圆形模型全散射轮廓的实验测量结果。我们首次报告了以等压点为特征的圆形结构典型反射光强行为的实验观察结果。我们之前提出了一种新的理论方法来测量圆柱形组织的全散射轮廓,即光强的角分布。在这项工作中,我们展示了实验结果与模拟结果相匹配。对于直径为7mm的圆柱形模型,我们在105°处显示了等压点,而对于直径为16mm的模型,等压点在125°。此外,实验工作还展示了不同直径圆柱形组织对象全散射轮廓的一个新的交叉点。
