棱镜

By using a linear array CCD normal to the axis of cylinder, the coordinate from the line to the basic shaft was measured.

采用转像棱镜使得像面发生90 的旋转，可以用同一个CCD测量该点的另一个坐标值。

In this paper, through the design of backrest and the relation of specific property and use of two binder s, the way of angle precision of prisms is guaranteed in the mass serial production is presented.

本文通过对靠体的设计和对二种粘结胶的特性及作用的论述，提出了在大批量生产中如何才能保证棱镜角度精度的方

There are times that they become barrel-shaped objects, and the ruby has a hexagonal prism.

有时候，他们成为圆桶形的对象和红宝石有六角棱镜。

Phase coefficients of the binary optical element are calculated.Primary configuration of telescope objective with reversing prism is ascertained.

计算了二元光学器件的相位系数，确定了含补偿棱镜望远物镜的初始结构。

Then according to the cascade of IPS and LPS, the multi-stage rearrangeable nonblocking Omega network was introduced. Moreover, the method of bipartition graph was adopted to ascertain the node state of each stage. At last, a module of the rearrangeable nonblocking Omega network, which was integrated with polarizing beam-splitter,λ/2 wave plate and perfect shuffle Plates, was constructed.

该方法通过逆混洗(Inverse Perfect Shuffle， IPS)和左混洗(Lott Perfect Shuffle， LPS)的串联，构成多级的可重排、无阻塞的Omega网络，采用二分图法依次确定各级节点开关的状态，最后通过偏振分光棱镜(Polarizing Beam Splitter， PBS)、半波片(λ/2 wave plate)和PS Plate的组合，得到可重排、无阻塞的Omega网络交换模块。

A rotatable biprism is introduced in phase mask technique to change the inscribed Bragg of grating.

将一种可旋转的双棱镜引入到相位掩模技术中以改变光栅的写入Bragg波长。

Measuring light wavelength with biprism interference is a very important experiment in the research and teaching of basic physics, the key to which is the distance measurement of the two virtual images.

用双棱镜干涉测量光波波长是基础物理研究和教学中非常重要的一个实验，该实验的关键环节是测量两虚相干光源间的距离，大多数实验教科书中大都采用二次成像法测量两虚相干光源的间距。

Because the change of grating period caused by the asymmetrical rotation of two beams is limited to 5×10-4 nm at a tunability of the Bragg wavelength of ~100 nm, the tilt of grating caused by the rotation of the biprism can be ignorable.

因为在~100 nm范围内两光束的非对称旋转对光栅周期的改变是5×10-4 nm，双棱镜引入的光栅的闪耀可忽略。

The crystals behave like glass prisms, splitting the light into a bow with the colours of the spectrum, often brighter than a rainbow.

那些晶体就像玻璃棱镜，将光分裂为带有色谱的弓形，常常比彩虹更亮。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
