From Seismology to Bridge Monitoring: Coda Wave Interferometry

Concrete is the most widely used building material in the world and its stability assessment is of utmost importance for society. Ultrasonic measurements are one tool for investigation of concrete stability. The goal of those measurements is the derivation of damage sensitive parameters. The way ultrasound diffuses through concrete is affected...

Detection of Hidden Cracks in Concrete Structures Using Reverse Time Migration of Ultrasonic Echo Data

Ultrasonic echo measurements are widely used in the field of non-destructive testing (NDT). In civil engineering, concrete structures are evaluated by this technique. Currently, Synthetic Aperture Focusing Technique (SAFT), a group of migration algorithms, is state of the art in ultrasonic data processing. Reverse Time Migration (RTM), recently...
