This is called interferometry, and is not a new idea.

这种方法被称为分析法，它不什么新想法。

As its name suggests, LIGO employs a technique called laser interferometry.

正如名称所示，LIGO采用了一种称为激光测的技术。

And this time, LIGO also has the support of KAGRA,   a new interferometry observatory in Hida, Japan.

这次，LIGO 还得到了位于日本飞驒市的新测天文台 KAGRA 的支持。

The EHT's trick is a technique called very long baseline array interferometry (VLBI).

事件视界望远镜的诀窍一种称为甚长基线测的技术。

This gives a very small glimpse into the relevance that holograms have to interferometry, which is the technique of using wave interference to measure extremely tiny distances.

这让我们稍微了解了全息图与仪之间的关联，仪利用波来测极小距离的技术。

Now, there is another application where you do actually have to fly over several times, and that's called interferometry satellite scanning, and that's the classical method, right?

现在， 有一种应用确实需要多次飞越，这被称为卫星扫描，这经典的方法， 对吧？

We're interfering waves together, that's what interferometry means and so if those waves move back and forth a little bit when you interfere them they destructively interfere and you lose your signal.

我们在进行波的，这就测法的意思。所以如果这些波在时前后移动一点点，它们就会产生破坏性，导致信号丢失。

The EHT gets around this by linking together 15-20 telescopes. It uses a technique known as interferometry, in which astronomers on different continents simultaneously observe the same object, then combine the collected data on a supercomputer.

而 EHT 通过连接 15-20 个望远镜来巧妙地应对这一问题。它使用了一种被称为" 测术" 的技术，用这种技术，在不同大陆的天文学家可以同时观测同一目标，然后将收集到的数据组合在一台超级计算机上。

They did a classical interferometry, Scan in other words to flyovers compared to look for interferences and they show that all three pyramids have indentations that's in the beginning of the pyramid paper.

他们做了一次经典的测，也就扫描飞越， 以寻找扰现象， 结果显示这三座金字塔在金字塔底部都有凹陷。

Born 1932, and Kip Thorne, born 1940. In 1967, while at MIT, Weiss developed the laser interferometry technique used by LIGO, working from the initial ideas of Joseph Weber, one of the inventors of the laser.

雷纳·韦斯， 1932年出生， 以及基普·索恩， 1940年出生。 1967年，韦斯在麻省理工学院期间，基于激光发明者之一约瑟夫·韦伯的初步构想，发展了LIGO所采用的激光测技术。
