The dual linear array (DLA) design incorporates two arrays of elements yet separates them with an acoustic barrier, so they can be used in pitch-catch mode like a UT dual-element transducer.

The transducer has to be shifted laterally across the test piece when a traditional flaw detector is used. On the other hand, a phased array system employs electronic scanning along a linear array ...

However, only convex array probes are used in acoustic structured illumination currently, and the sound field designed is inconsistent with the commonly used structured illumination light of moire ...

The array used in this study, as shown in Figure 2B, consists of two identical customized unfocused linear array probes (TomoWave Inc., Houston, United States). Each subprobe has 48 elements of 1.0 mm ...

Using the proposed method, a linear array is calibrated in an experimental reflective environment, with a probe scanning aperture covering 1/3 of the AUT aperture. The results indicate a calibration ...
