2D phased arrays possess the additional advantage of steering the generated ultrasound beam in three dimensions at arbitrary focal lengths, which can be used for detailed localized imaging2,3. Among many imaging applications, ultrasound has been demonstrated as a viable modality to help diagnose bone ...
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...

Arrays provide flexibility not possible with solid apertures. By the control of the delay and weighting of each element of an array, beams can be focused electronically at different depths and steered or shifted automatically. Lateral resolution and beam-shaping can also be changed through adjustment...

The two techniques presented are novel tools that are applicable for imaging the atmosphere. Validation of the techniques are applied using previously collected real data from the Turbulent Eddy Profiler. Preliminary results of the first technique show improved power estimation compared to Capon beam...

If a source existed at the angle occupied by point D, then point A would indicate the gain with which the system would process that source. [0019] One problem with beam-steered systems is that a noise source, such as an air conditioner or idling delivery truck, can exist within the ...
