正交偏振 [电子] cross-polarization
crossed nicols
- 其中,评价病变颜色的方法有正交偏振漫反射成像系统、红斑指数评价法;
Cross- polarized diffuse reflectance imaging and erythema index measured by reflectance spectra can measure the color of PWS skin. - 利用基于该原理的正交偏振光谱成像仪器进行了实验,得到对比度清晰的甲襞微循环图像。
The experiments are done with orthogonal polarization spectral imaging apparatus based on this theory and some nail-fold microcirculation images with good contrast are obtained. - 本文介绍了一种新型的棱镜形的四端口正交偏振光合波器(PBS),它具有很高的消光比,较低的插入损耗,同时还具有抗光损伤阈值大、使用波段宽、物理化学性能稳定等优点。
This dissertation introduces to you a novel prism orthogonal PBS with high extinction ratio, low insert loss, and it has high power threshold, wide bandwidth and stable characteristics.
