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

事件视界望远镜的诀窍是一种称为甚长基线干涉测量的技术。

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

其名称所示，LIGO采用一种称为激光干涉测量的技术。

This is essentially  what the interferometer measures with light.

这本质上就是干涉仪用光测量的内容。

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

这次，LIGO 还得到位于日本飞驒市的新干涉测量天文台 KAGRA 的支持。

This squeezing  minimizes the light's phase noise and squeezes it into amplitude noise, which the interferometer  doesn't measure.

这种挤压最大限度减少光的相位噪声，并将其挤压成干涉仪无法测量的振幅噪声。

Ye then launched her VLBI project at the observatory, but the research funding would not stretch to the 25-metre radio telescope that was needed.

叶老师随后在天文台启动她的甚长基线干涉测量项目，但研究资金不会延伸到所需的 25 米射电望远镜。

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.

这让我们稍全息图与干涉仪之间的关联，干涉仪是利用波干涉来测量极小距离的技术。

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 个望远镜来巧妙应对这一问题。它使用一种被称为" 干涉测量术" 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。

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.

我们在进行波的干涉，这就是干涉测量法的意思。所以果这些波在干涉时前后移动一点点，它们就会产生破坏性干涉，导致信号丢失。

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.

他们做一次经典的干涉测量，也就是扫描飞越， 以寻找干扰现象， 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LIGO所采用的激光干涉测量技术。
