Light emitted and reflected by objects provides us with much useful information about our surroundings. In addition to its wavelength and intensity, one very useful property of an optical beam is its polarization state, or the orientation of the electric field vector perpendicular to the propagation direction. When light travels through an object, its polarization state will be changed. Hence the properties of the object can be obtained through the change in the polarization state. We propose to extend our research into polarized light interactions with turbid materials. The long-term goal of the research is to perform polarized light assessment of biological tissues.

物体发出和反射的光为我们提供了关于周围环境的许多有用信息。除了它的波长和强度，光束的一个非常有用的特性是它的偏振状态，或者垂直于传播方向的电场矢量的方向。当光穿过物体时，其偏振态会发生变化。因此，物体的性质可以通过偏振态的变化来获得。我们建议将我们的研究扩展到偏振光与混浊材料的相互作用。 该研究的长期目标是对生物组织进行偏振光评估。
