Eddy current measurements using optically pumped magnetometers

使用OPM的涡流测量可以确定物体的导电性，因为初级场在感兴趣的物体中感应涡流。这又会产生感应磁场，可以使用OPM检测到。目前，我们正在努力建立一个便携式OPM，以便它可以测试生物医学和国防应用。我目前的工作涉及设计和构建便携式OPM的理论和实验工作，以及预计将在未来几个月内进行实验测量的信号。

Eddy current measurements using OPMs can determine the conductivity of objects, as a primary field induces eddy currents in the object of interest. This in turn produces an induced magnetic field, which can be detected using an OPM. Currently, we are working on building a portable OPM, such that it can be tested for biomedical and defence applications. My work currently involves theoretical and experimental work on designing and building the portable OPM, as well as the signals that will be expected to be measured experimentally in the coming months.
