一束光

It's kind of like the way a lens magnifies a beam of light.

它是一种象一种能放大一束光的方法。

To measure the refractive indices of different parts of a cell they use a technique called interferometry, which involves splitting a beam of light in two. One half, known as the object beam, passes through the cell; the other is directed along a different path and acts as a reference.

为了测量细胞各部分的折射率，他们采用了一种名为干涉测量法的技术，将一束光分为两束，其中一束通过细胞，被称为物体光束；另一束光则沿不同路径作为参考光束。

Using a specially designed keyboard in conjunction with state-of-the-art light sensor technology, a hand or head pointer controls a beam of light that enters, then confirms, the key or mouse function.

特殊设计的键盘采用了光传感器技术，位于手或是头部的指示器控制一束光进行回车，然后确认，其功能就和鼠标键盘一样。

This article presents a new method of reflected holographic interferometry using a single beam.

本文论述一种一束光反射式全息干涉方法。

A beam of light (typically ultraviolet light from a mercury arc lamp) shines through the chromium mask, then passes through a lens that focuses the image onto a photosensitive coating of organic polymer on the surface of a silicon

一束光（通常是汞弧灯发出的紫外光）先穿透铬光罩，然后通过透镜把影像聚焦在晶圆表面的有机高分子感光涂料。

一束光（通常是汞弧灯发出的紫外光）先穿透铬光罩，然后通过透镜把影像聚焦在晶圆表面的有机高分子感光涂料。

All optical switches use the third-order optical nonlinearity of materials, whose work principle can be described as follows. One laser beam inducing the change of refractive index of materials, signal beam transmitted in mate rials will produce accessional phase change to realizing the "On" or "Off" ofoptical switches.

全光开关的工作原理利用了材料的三阶非线性光学特性，用一束光引起材料的折射率发生变化，信号光在其中通过时就会带来相位的变化，从而实现光开关的开关动作。

A drop of water contains the essence of the ocean, a bunch of light reflected the shining glory of the sun, a small matter also can refract a person's accomplishment.

一滴水蕴藏着大海的本质，一束光反映了太阳的光辉，一件小事也能折射出一个人的修养。

A light source with reflectors that projects a beam of light in a particular direction.

装有能投射到某一特定方向一束光的反射镜的灯。

Although it was only off by 2.2 micrometres, this badly blurred the telescope's vision and made the scientists who had promised the world new images and science in exchange for $1.5 billion of public money the butt of jokes.

格瑞尼在2008年说伽利略观测到的星图其实是叫做艾利斑的衍射图像，艾利斑是指一束光通过一个小孔时得到的同心圆图像，就像一束星光通过一个小孔时呈现的图像。

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。
