New Developments in IR Lock-In Thermography [PDF]
International Symposium for Testing and Failure Analysis, 2004 Abstract Lock-in thermography based on an infrared camera has proven to be a useful tool for failure analysis of integrated circuits (ICs). This article discusses four novel technical developments of lock-in thermography. These developments are blackening the IC surface with colloidal bismuth, the synchronous undersampling technique ...

Laser lock-in thermography on dental inspection [PDF]
AIP Conference Proceedings, 2019 Detection of cracks in teeth and the evaluation of a dental restoration in a non-invasive way is of paramount importance in clinical practice. Common dental X-ray diagnosis is precise but causes a lot of concerns due to its ionizing radiation nature, not-so-comfortable patient experiences, as well as used-in-caution for women in pregnancy, etc.
