超高感度非破壊検査技術

Ultra-sensitive Non-destructive Testing and Evaluation Technology

非破壊検査とは構造物を壊すことなく健全性を評価するための方法です。

私たちの研究グループでは磁気を用いた新しい超高感度な非破壊検査技術の開発を行っています。

Non-destructive testing is an analysis technique used to evaluate health of the infrastructures without causing damage.

We, our research group, have been developing new ultra-sensitive non-destructive testing methods making use of magnetic field.
