Fourier-domain beamforming for Full Matrix Capture Data with Circular Statistics Vector Weighting in Nondestructive Testing [PDF]

, 2023
Abstract Total focusing method (TFM) based on full-matrix capture (FMC) is widely used in the field of nondestructive testing due to its high resolution and high signal-to-noise ratio. In order to solve the problems of the slow speed of traditional time-domain total focusing imaging and poor imaging quality, this paper proposes a total focusing

Advanced Photoacoustic Imaging Using Full Matrix Capture Data Acquisition

, 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.

An Inverse Approach for Ultrasonic Imaging From Full Matrix Capture Data: Application to Resolution Enhancement in NDT [PDF]

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2020
In the context of nondestructive testing (NDT), this article proposes an inverse problem approach for the reconstruction of high-resolution ultrasonic images from full matrix capture (FMC) data sets. We build a linear model that links the FMC data, i.e., the signals collected from all transmitter-receiver pairs of an ultrasonic array, to the ...

Adapting the full matrix capture and the Total Focusing Method to laser ultrasonics for remote non destructive testing [PDF]

2017 IEEE International Ultrasonics Symposium (IUS), 2017
Laser Induced Phased Arrays (LIPAs) use post processing to focus and steer the laser generated and detected ultrasonic beam, synthesizing a phased array. The technique is broadband, non-contact, and couplant free, making LIPAs suitable for large stand-off distances, inspection of components of complex geometries and hazardous environments.

Ultrasonic Phased Array Imaging Approach Using Omni-Directional Velocity Correction for Quantitative Evaluation of Delamination in Composite Structure

Sensors, 2023
The ultrasonic detectability of buried defects within composite materials is dependent on the anisotropy of the composite material by which the propagation property of acoustic wave in each direction is variably affected.
