A model-based study of transmit-receive longitudinal arrays for inspection of subsurface defects

Research output: Contribution to conferencePaper

Abstract

Dual matrix transmit-receive longitudinal arrays have been shown to have an improved signal to noise ratio in near field zone which makes them the most suitable array configuration for inspection of near surface defects. This study aims to compare the performance of different configurations for transmit-receive longitudinal matrix arrays. For this purpose, 4 matrix configurations of 2×32, 4×16, 4×32, and 8×16 elements are investigated using CIVA modelling. The array operating frequencies investigated are either 5 MHz or 10 MHz. Different natural focal depths for these TRL arrays are considered in the model. For each configuration, the ability to steer and skew the beam is examined through CIVA modelling of the inspection of flat bottom holes extended to a few millimeters under the surface. It is found that the focusing for near surface areas is more efficient using the 4×16 and 8×16 elements configurations.
