Pulse Peak Delay-Total Focusing Method for Ultrasonic Tomography on Concrete Structure
Applied Sciences, 2021 An ultrasonic array device like the A1040 MIRA is used to non-destructively visualize the inside of concrete structures. A data set acquired by the ultrasonic array device is so unfocused that an image reconstruction algorithm is required to transform ...

Enhanced Near-Surface Flaw Detection in Additively Manufactured Metal Ti-5Al-5V-5Mo-3Cr Using the Total Focusing Method [PDF]
SensorsAdditive manufacturing (AM) enables the fabrication of complex components with high geometric freedom, but it can introduce near-surface flaws due to rapid solidification, resulting in porosity and lack of fusion. In addition, localized melting and steep

Total Focusing Method Based Ultrasonic Phased Array Imaging in Thick Structures [PDF]
Journal of Nondestructive Evaluation, Diagnostics and Prognostics of Engineering Systems, 2021 Abstract Ultrasonic non-destructive testing traditionally uses a conventional monolithic transducer. An approach similar to this comprising of independent single transmissions but with reception performed by all the elements in phased array ultrasonics is known as Full Matrix Capture (FMC).
