... there is a narrow window of time in which defects heat locally but do not spread laterally losing contrast. One solution is lock-in thermography (LIT). LIT is a well-established failure analysis tool and is typically done with infrared (IR) cameras. [1] LIT techniques provide a wide rang of applications...
