Study on Enhancements to Ultrasonic Data Imaging Using Full Matrix Capture Technique
Journal of the Korean Society for Nondestructive Testing, 2015 Abstract A conventional phased array system can control an ultrasonic beam electronically by adjusting the excitation time delay of individual elements in a multi-element probe and produce an ultrasonic image. In Contrast, full matrix capture (FMC) is a data acquisition process that allows receiving ultrasonic signals from one single shot of the phased

Diffuse field full matrix capture for near surface ultrasonic imaging [PDF]
Ultrasonics, 2018 This article reports a technique for near-surface ultrasonic array imaging. Information equivalent to an undelayed full matrix of inter-element responses is produced through cross-correlation of a later time diffuse full matrix. This reconstructed full matrix lacks the nonlinear effects of early time saturation present in a directly acquired response ...
