摘要：Electromagnetic induction imaging (EMI) is a well-established imaging technique, developed over several decades. It has been widely used to assess cracks in metallic structures and to detect and localise buried metallic objects. In its standard configuration, EMI’s remit of application is severely restricted by the poor sensitivity of the sensing coil at low frequency. This prevents the exploration of interesting applications where low-frequency operation and/or extreme sensitivity is required, such as through-barrier imaging or imaging of human organs. The demonstration in 2014 of the use of an atomic magnetometer (AM) as sensor for EMI completely changed this scenario, and opened up new perspectives for EMI, as atomic magnetometers maintain their extreme sensitivity at low frequency. This talk discusses challenges and opportunities of EMI-AM in many sectors, from medicine to security and industrial monitoring.
