Automated full matrix capture for industrial processes [PDF]

open access: yesAIP Conference Proceedings, 2015
Full matrix capture (FMC) ultrasound can be used to generate a permanent re-focusable record of data describing the geometry of a part; a valuable asset for an inspection process. FMC is a desirable acquisition mode for automated scanning of complex geometries, as it allows compensation for surface shape in post processing and application of the total ...

Compressive sensing of ultrasonic array data with full matrix capture in nozzle welds inspection

Ultrasonics, 2023
The phased array ultrasonic technique (PAUT) with full matrix capture (FMC) exhibits the advantages of high imaging accuracy and great defect characterization ability, which play important roles in the nondestructive testing of welded structures. To address the problem of a large amount of signal acquisition, storage, and transmission data in nozzle ...

Advanced Photoacoustic Imaging Using Full Matrix Capture Data Acquisition [PDF]

open access: yes, 2015
Full Matrix Capture (FMC), when used with the Total Focusing Method (TFM), may offer an improvement on the Synthetic Aperture Focusing Technique (SAFT) algorithm. FMC is a data acquisition process which captures A-scan (time-amplitude) data for every transmitterreceiver combination of elements in an array.

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.
