Phased array ultrasonic testing (PAUT) is an ultrasonic imaging detection technology that implements functions such as ultrasonic beam movement, deflection, and focusing by applying different time delay rules, that is, the focal law, to different units of the transducer array when emitting or receivin...

If prearranged phase delays are introduced in the firing of the signals of individual array elements, then the constructive interference beam can be steered to difference angular positions. Thus, an azimuth and elevation sweep can be achieved without mechanical rotation of the radar platform. The ...
imaging performance of the conformable array on phantom soft matter of various shapes, with and without phase correction. The FlexArray demonstrates controllable beam steering functionality and operational pressures of > 500 kPa at the focal point, at a resonant driving frequency of ~ 1.4 ...
The interferograms obtained are then spatially heterodyne-detected on a computer to extract the signal components, that is, array data. Then, the eigenvector of the largest eigenvalue is derived by applying the power method to the array data and it is beam-steered to get images of the object...
(typically 5–20 µm) to avoid misalignment. As mentioned, while a handful of previous TFT demonstrations have achievedfMAXabove gigahertz values44,46,47,52,53, these relied on processing not compatible with large-area electronics, such as electron-beam lithography, to pattern short channels ...
