專利摘要(中)
一種渦電流感測方法包含:對第一線圈提供激發訊號;第一線圈因激發訊號產生第一電磁訊號;第一電磁訊號耦合至第二線圈,使第二線圈產生第二電磁訊號;當導體物接收第一電磁訊號或第二電磁訊號後產生感應渦電流,感應渦電流至少部分抵銷第二線圈的第二電磁訊號;以及經由第二線圈量測第二電磁訊號被至少部分抵銷後的變化量以判斷導體物的狀態。
專利摘要(英)
A method for eddy current induction detection comprises: providing an excitation signal to a first coil; the first coil generates a first electromagnetic signal due to the excitation signal; the first electromagnetic signal is coupled to a second coil, and causing the second coil to generate a second electromagnetic signal; when a target conductor receives the first electromagnetic signal or the second electromagnetic signal, the target conductor will generate an induced eddy current, the induced eddy current at least partially offsets the second electromagnetic signal of the second coil; and measuring the change in the second electromagnetic signal after at least partial cancellation through the second coil to determine the state of the target conductor.
