Eddy current measurements using optically pumped magnetometers

使用光学显微镜的涡流测量可以确定物体的电导率，因为主场在感兴趣的物体中感应涡流。这反过来会产生感应磁场，可以使用OPM检测到。目前，我们正在建造一种便携式OPM，这样它就可以在生物医学和国防应用中进行测试。我目前的工作包括设计和建造便携式OPM的理论和实验工作，以及预计将在未来几个月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.
