在本文中，我们开发了一种新的磁成像系统，用于材料结构和力学条件的无损评估。这产生了各种磁特性的空间变化的多参数等值线图，例如矫顽力、剩磁、磁导率和巴克豪森效应信号。此外，我们已经开发出一个集成的传感器探头能够测量磁滞和BE信号使用磁阻器件。
In this paper, we develop a new magnetic imaging system for non-destructive evaluation of structural and mechanical conditions of materials. This produces a multi-parameter contour plot of the spatial variations of variety of magnetic properties such as coercivity, remanence, permeability and Barkhausen effect signal. Also we have developed an integrated sensor probe capable of measuring both magnetic hysteresis and BE signals using magnetoresistive devices.
