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.

Phased Array Systems Traditional ultrasonic transducers for nondestructive testing generally include a single active element or two paired elements. On the other hand, phased array probes include a ...

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 ...

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 ...
