基于虚拟项目驱动的人文公共基础课建设思路探讨——以《沟通与演讲》课程为例

人文公共基础课在高职院校普遍处于基础薄弱、被边缘、被忽视的尴尬境地,缺少专业课那样便利的工学结合条件。因而如何做好该类课程建设,一直是各高职院校比较头疼的问题。我院人文基础课建设中引入“虚拟项目驱动”教学思想,建立了以“两赛三练一室一协会”的实践教学模式。本文即是对该项课改工作的思路总结与实践探讨。     

Towards skin polarization characterization using polarimetric technique

Measurement of optical properties of skin is an expanding and growing field of research. Recent studies have shown that the biological tissue, especially skin, changes the polarization state of the incident light. Using this property will enable the study of abnormalities and diseases that alter not only the light intensity but also its polarization state. In this paper we report an experimental study for measuring changes of polarization state of the light scattered from a phantom similar to a sample model of scattering skin. Using the notation of Stokes vector for the polarized light and Mueller matrix for the sample with its polarization properties, we have shown that some elements of the matrix were particularly sensitive to the changes of the polarization-altering physical properties of the scatterers within the phantom.
