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).

VARIABLE SPLIT APERTURE PROCESSING OF FULL MATRIX CAPTURE PHASED ARRAY DATA

AIP Conference Proceedings, 2011
Work is being conducted to develop phased array inspection of stainless steel welded pipes. Defects can occur anywhere along the weld fusion face. Optimum inspection performance across the entire weld face can be facilitated by collecting data as Full Matrix Capture (FMC) and applying a processing technique that allows focusing to be ideal for every ...

Study on the railway wheel ultrasonic inspection method using the full matrix capture

2013 Far East Forum on Nondestructive Evaluation/Testing: New Technology and Application, 2013
The quality of wheel is especially important for the safety of high speed railway. In this paper, a new ultrasonic array inspection method, the Full Matrix Capture (FMC) and Total Focus Method (TFM) algorithm, has been studied and applied to the high speed railway wheel inspection, especially in the wheel web from the tread.

THROUGH-WELD ULTRASONIC PHASED ARRAY INSPECTION USING FULL MATRIX CAPTURE

AIP Conference Proceedings, 2010
Rolls‐Royce and Imperial College are developing phased array inspections for welded stainless steel piping with an undressed weld cap. An inspection that proves particularly challenging requires ultrasonic waves to propagate across the irregular weld‐cap profile, and through the structurally complex weld material.

THE WAVENUMBER ALGORITHM: FAST FOURIER-DOMAIN IMAGING USING FULL MATRIX CAPTURE

AIP Conference Proceedings, 2009
We develop a Fourier‐domain approach to full matrix imaging based on the wavenumber algorithm used in synthetic aperture radar and sonar. The extension to the wavenumber algorithm for full matrix capture is described and the performance of the new algorithm is compared to the total focusing method (TFM), which we use as a representative benchmark for ...

The efficiency optimization of full matrix capture imaging detection based on increasing the effective aperture

2014 IEEE Far East Forum on Nondestructive Evaluation/Testing, 2014
The Full Matrix Capture (FMC) method can provide the original complete information which is detected by the ultrasonic array and can recover with the Total Focusing Method (TFM). This technique has better detection sensitivity and resolution relative to conventional scanning method and is valuable for improving the quality and reliability of industrial
