... materials until it reaches the device surface. At the surface, this thermal energy forms a hot-spot from which it radiates off as infrared waves that are detected by an IR-sensitive camera. Despite the degradation in lateral resolution owed to lateral spreading of the thermal wave, lock-in thermography does...

... 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 for qualitative and quantitative analysis of solar...

... local heat sources due to electrical shorting. In the past decade, Thermography has been further adapted by using Lock-in techniques that enable a highly improved spatial resolution down to single micrometer and a sensitivity within microwatt range [9] . The general setup consists of a mid-wave IR...
