This frequency difference gives rise to a beat frequency. The envelope of the beat frequency is depicted as the grey areas. The envelope of the beat frequency will always be stationary in space; no angular velocity. The beat frequency can be thought of as an interference pattern in time, as opposed to the spatial interference pattern that is obtained with a passive Sagnac interferometer. The envelope of the beat frequency can be thought of as a string of beads. A wave energy detector that is co-rotating with the device will travel along the envelope of the beat frequency, passing the "beads" one by one. The faster the rotation rate of the device, the more beads will come along. 软件翻译: 这种频率差异引发的摆动频率。信封的摆动频率是描述的灰色地带。信封的摆动频率将永远固定在空间;没有角速度。节拍频率可以被认为是干涉模式的时间,而不是干涉的空间格局是获得了一个被动Sagnac干涉仪。信封的摆动频率可以被认为是一连串的珠子。 A波探测器的能源是共同的旋转装置将沿信封的摆动频率,通过了“珠”一个接一个。更快的自转速率的设备,更多的珠子会沿着。 fuj0翻译: . 是两束光是行波。 形成的拍频(beat frequence)的信封(envelop, 有外包装的意思,确切物理名词不详)可以描述成灰色的波状图。这个波没有角速度,相对于实验室系静止。可以看成是两个行波在时间上的干涉,不是空间上的干涉。测频器随波源转动,转动越快,受到的拍频的头数越多。 ※※※※※※ 流水和气流不会改变其中超声波束的传播方向——动煤质波动理论呼之欲出! |
