查询词典 immersion lens

The simulation result shows the collection efficiency of TIR lens model is 67% when the angle of light is confined within 15°. And the uniformity on observation screen is improved in some degree. The optimal design of TIR lens further provides the development space of LED micro-projection display system.4 On the base of the theory research and the model simulation, four projection display systems which have LCOS as micro-display panel and which combine different optical devise for UHP and LED light source respectively are proposed in this dissertation. And the quality of projection display system is evaluated by thesimulation outcome.

模拟结果表明，优化后的TIR透镜可实现将LED大角度扩展光束中67％的光能压缩到15°范围以内，并使目标屏的照明均匀性得到一定的改善，这为LED光源微投影显示系统设计提供了新的发展空间。4在以上理论研究和模拟分析的基础上，将优化和改造得到的照明光学元件应用到微投影显示的照明系统设计中，分别采用UHP和LED光源，设计了四套单片式LCOS微投影显示系统模型，通过光线追迹模拟结果，对系统性能进行了评价分析和对比。

The peak of this curve is the maximal sensitivity of SCE. Because the shape of SCE is highly related to the location of the crystalline lens in the internal ocular space, we can therefore study the relative displacement of the lens while on accommodation through the comparisons of the SCE at different accommodative stages.

因SCE图形的峰值位置和水晶体的位置相关，所以我们可藉由调视前后SCE图形的变化来探讨水晶体在调节时视觉光轴的变化。

A beam splitter is mounted on the substrate on a center line between elongations of the optical fibers, and light emitted from the lens portion propagates through space and is launched in focused form into the beam splitter, and a portion of the incident light is reflected, which propagates space and is launched in focused form into the lens portion and propagates through the optical fiber.

分光器(31)安装在基底(11)上并位于光纤(21)和(22)延长线之间的中心线(25)上，从透镜部分(21a)发射的光穿过空间并以聚焦的形式入射到分光器(31)，一部分该入射光被反射，该光穿过空间并以聚焦的形式入射到透镜部分(22a)、并穿过光纤(22)传送。

In the modern movies by the fifth generation directors, which emphasize medium experiment, the lens tries all language rules possibly. The extreme lens space explains the natural space; the aesthetic space conquers the natural space. Or the offscreen space is actively used to recount. The sixth generation directors even have a tendency to ignore the image space.

在第五代导演这批强调媒介实验性的现代电影中，镜头尽可能地尝试着所有的语言规则，以极端的镜头空间诠释着自然空间，以审美空间征服自然空间；或积极运用画外空间叙事，第六代导演甚至出现了漠视物象空间的倾向。

The linewidth error of 16-step Fresnel lens is measured and its effect on 16-step Fresnel lens is analyzed.

通过实验测量16阶菲涅耳透镜的线宽误差，分析其对16阶菲涅耳透镜衍射效率的影响。

Lens luxation is a displacement of the lens from its normal position.

晶状体脱位是指晶状体从正常部位脱离。

A device,such as a monocle or spyglass,containing a lens or lens es and used as an aid to vision.

透镜含一个或多个透镜，用于辅助视力的一种工具，如单片眼镜或小望远镜

Tne paper systemically discusses the object-image relations in the thin-lens imasery with Newton Formula and the relative graphs,and new and deeper theoretical otplanations are given. Thin-lens imasery Newton Formula,graph velation

Object and t he lens, s' is the distance between the i mage and the lens, and f is the distance

s是物体和透镜之间的距离，s' 是影像和透镜之间的距离

When the measuring system of point scanning confocal microscope is designed,the parameter of object lens is important because the measuring precision of the system are determined by the numerical aperture of lens.

在设计点扫描激光共焦显微镜测量系统时，物镜参数的选择是至关重要的，因为它的数值孔径大小直接影响着系统的测量精度。

Alternatively, the con- trollers can use the synchronous rectifier itself or loss- less inductor current-sensing methods to provide overload protection with lower power dissipation.

另外，康威特罗勒斯可以使用同步整流器本身或亏损减少电感电流检测方法，以提供低功耗过载保护。
