Interferometer

释义 Definition

干涉仪:一种利用波(常见为光、微波或声波)相互干涉产生的条纹/信号来进行精密测量的仪器,可用于测量长度、位移、折射率、表面形貌、振动或极小的相位差等。

发音 Pronunciation (IPA)

/n.tr.fr.m.tr/(美式常见)
/n.t.fr.m.t/(英式常见)

例句 Examples

The interferometer measures tiny changes in distance.
干涉仪能测量极微小的距离变化。

By analyzing the interference pattern, the interferometer can detect vibrations smaller than a wavelength of light.
通过分析干涉条纹,干涉仪可以检测到比光的波长还要小的振动。

词源 Etymology

interferometerinterfere(干涉) + -meter(测量器/计量器) 构成,字面意思是“用干涉来测量的仪器”。其中 interfere 源自拉丁语系词根,含“相互介入/交叉影响”之意;**-meter** 来自希腊语 metron(“测量”)。
