Theoretical calculation and experimental results illustrate that polarized light can be used to study the twist effect in thin sample of planar nematic liquid crystal.

This new mechanism is more interesting for applications because it raises the possibility of optically aligning and manipulating both isotropic and anisotropic transparent bodies using, eventually, unpolarized light.

这个新的机械装置在应用上引起了越来越多的人的兴趣，因为它增加了在各向同性和各向异性介质中使用非偏振光进行光学娇正和操作的可能性。

We have seen that, when unpolarized light is reflected, there is a preferential reflection for light polarized perpendicular to the plane of incidence.

如图42-4所示。我们看到，当非偏振光反射后，就会有偏振光从垂直于入射面的方向反射出来。

The results of experimental and theoretical study indicate that the unpolarized light from He-Ne laser is equivalent to circular polarized light.

实验和理论研究的结果都说明由氦氖气体激光器发出的非偏振光是和圆偏振光等效的。

The method utilizes an optical device which consists of polarization control elements and polarization beam splitting pieces for realizing the multi-switching of polarization or non-polarization light; in a position sequence, one polarization beam splitting piece is arranged on a main optical path at the back surface of each polarization control element, thereby commonly constituting a 'single-pole double-throw' optical switch with a controller; the controller changes the polarization state of input light beams by driving the polarization control elements according to the control logic, and the input light beams are switched to any one path on an output channel through the polarization beam splitting pieces, thereby completing the designated optical information processing function.

利用偏振控制元件和偏振分束片两种光学元件组成的光学装置实现偏振或非偏振光的多路切换；在位置序列上，每个偏振控制元件后面主光路上放置一块偏振分束片，并和控制器共同构成一个'单刀双掷'光开关；控制器按照控制逻辑驱动偏振控制元件改变输入光束的偏振态，并通过偏振分束片将输入光束切换到输出通道上的任何一路，来完成指定的光信息处理功能。

In other words, if an analyzer alone is used to analyze circularly polarized light, it will give the same result as when used to analyze unpolarized light.

另一方面，如果使用非偏振光独自进入分析器时，这也会有同样的结果。

Optical filters under unpolarized light, as well as by illumination with polarized light.

这个标记可以被侦测得到，和/或可以用被动侦测方法，例如在非偏振光下，用光学过滤器来侦测，或者用偏振光来照明。

The position of the first or second lens can be adjustable for calibrating the focus of the unpolarized light onto the PBS array. Alternatively, both lenses can be adjustable.

第一和第二透镜的位置可以设置从而调整非偏振光在偏振光束分束器阵列上的聚焦。

The system can be calibrated by adjusting the position of at least one lens to focus unpolarized light onto the PBS array, thereby reducing reflection of the unpolarized light from the polarizing beam splitter array.

该系统可以通过设置至少一个透镜的位置调整，从而将非偏振光聚焦在偏振光束分束器阵列上，由此减少反射。

After unpolarized light traverses the polarizer, it is linearly polarized, with the polarization direction parallel to the broken line on the polarizer.

非偏振光传到起偏器后，变为线偏振光，在起偏器中我们用短线表示偏振化方向。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
