Laser ultrasonic imaging of complex defects with full-matrix capture and deep-learning extraction
Ultrasonics, 2023 Phased array-based full-matrix ultrasonic imaging has been the golden standard for the non-destructive evaluation of critical components. However, the piezoelectric phased array cannot be applied in hazardous environments and online monitoring due to its couplant requirement.

Improved Inspection Through Full Matrix Capture Technology
Volume 1: Pipeline and Facilities Integrity, 2020 Abstract The ideal Non Destructive Evaluation/Examination process should be carried out using a fully automated system: planning, execution, evaluation and reporting would be all tasks performed by automated technologies and artificial intelligence that don’t need human intervention, thus taking the Human Factor out of the equation.

Full-matrix capture with a customizable phased array instrument
AIP Conference Proceedings, 2015 In recent years, a technique known as Full-Matrix Capture (FMC) has gained some headway in the NDE community for phased array applications. It's important to understand that FMC is the method that the instrumentation acquires the ultrasonic signals, but further post-processing is required in software to create a meaningful image for a particular ...

A GPU-Based Portable Phased-Array System with Full-Matrix Capture
2018 IEEE International Ultrasonics Symposium (IUS), 2018 The widely adopted ultrasound Phased-Array (PA) systems for nondestructive testing (NDT) use standard beamforming for line-by-line image creation. The introduction of the new full-matrix capture (FMC) technique enables the implementation of advanced processing algorithms (e.g. the total focusing method, multi-pass adaptive techniques).
