The researchers said an observation method called gravitational lensing also helped them.

That unblinkingly vivid Japanese sun seems the blazing focus of the glassy ocean's immeasurable burning-glass.

那眨不眨生机太阳似乎就是这玻璃般大洋巨大凸透镜燃烧焦点。

And although a second satellite containing the " eyepiece" (a special lens that also uses Fresnel optics, and a camera to record the image) must fly at the focus, the accuracy required is only hundredths of a metre, not billionths.

并，尽管还必须有个含有" 目镜" （也是运用菲涅尔视觉特殊透镜，也是录图像相机）卫星在焦点上运行，所需要精准度也只是百分之米。

The laser beam is born in these machines down in the basement, and it's directed through a maze of lenses and devices that shape and monitor it.

激光束在地下室这些机器中产生，并通过迷宫般透镜和设备来塑造和监控它。

(a special lens that also uses Fresnel optics, and a camera to record the image) must fly at the focus, the accuracy required is only hundredths of a metre, not billionths.

（也是运用菲涅尔视觉特殊透镜，也是录图像相机）卫星在焦点上运行，所需要精准度也只是百分之米。

When multiple of these lenticular sheets with different lens distributions are layered in just the right way, they are able to refract light at a myriad different angles to create " dead spots " .

将许多这在不同位置配有透镜柱状透镜以适当方式分层堆放，就能折射出千千万万光线角度，从而制造视觉" 死角" 。

So there are sort of variants of TNT called explosive lenses, and they are putting them around the plutonium sphere that powers the whole thing.

这是叫做爆炸透镜 TNT 变体，他们把它们放在钚球周围提供动力。

It has three billion pixels, a five-foot-wide optical lens, and it took scientists at the SLAC National Accelerator Lab nearly two decades to build it.

它拥有30亿像素，配有个5英尺宽光学透镜，美国能源部斯坦福直线加速器（SLAC）国家加速实验室科学家们用时近20年打造出了这台相机。

Besides saving weight and volume, Dr Yu's flat lenses also promise to be cheaper to mass produce than the conventional sort.

除了重量和体积，虞博士还承诺他平面透镜比批量生产传统类型更便宜。

Here is your lens that makes the microscope function properly.

这是让显微镜正常工作透镜。

He said the group plans to use the ring to also study " dark matter substructures" within the lensing galaxy.

他说，该小组计划利用该环来研究透镜星系内“暗物质子结构”。

There are two main flavors of telescope: refractors, which use a lens, and reflectors, which use a mirror.

使用透镜折射镜和使用单面镜反射镜。

And that mass predicts the deflection angle for light passing the Sun perfectly, that is its gravitational lensing effect.

而这个质量完美地预测了光线经过太阳时偏转角度，也就是太阳引力透镜效应。

The key is the smartphone's camera and processing power combined with the lenses and filters located in the cradle.

该技术关键在于把智能手机摄像头和处理能力，以及支架中透镜和滤光片整合起来。

The lenses send more light where it should be and that reduces light pollution and saves money.

透镜把更多光送到我们想要它在地方，这样就减少了光污染，同时也节省了钱。

One of the main criticisms of the HoloLens 1 was it's limited field of view.

对于第代全息透镜主要批评之是它有限视野。
