Investigation on a new inducer of pulsed eddy current thermography

AIP Advances, 2016
In this paper, a new inducer of pulsed eddy current thermography (PECT) is presented. The use of the inducer can help avoid the problem of blocking the infrared (IR) camera’s view in eddy current thermography technique.
