Abstract :
Thermal Laser Stimulation images are normally acquired using an averaging scheme to improve signal detection. However it does not work well when strong perturbation signals are present. For these cases correlation methods, which are more effective at extracting weak signals embedded in strong perturbations, become more important for TLS techniques.
