Study of multi-long-pulse thermography using high-power fiber lasers

AIP Advances, 2023
Active infrared thermography tests are performed using a high-power continuous fiber laser as the excitation source. Multi-long-pulses (MLPs) are used to detect deep defects in samples with reduced heating.

Lock-in and pulsed thermography for solar cell testing [PDF]

Applied Optics, 2018
Inspection of solar cells is an important part of their production process because even small defects can cause a significant drop of a whole photovoltaic module performance. LED illuminated lock-in (LEDILIT) and flash-pulse thermographic techniques (FPT) were compared in this study. Lock-in methods are more commonly used for solar cell inspection. The
