DACON ULTRASONIC PHASED ARRAY Ultrasonic Phased Array originated as early as 1959 wheb Tom Brown at Kelvin and Hughes filed for a patentof an annular dynamically focussed transducer system. This system latterly became known as phased array. Ultrasonic technology has evolved from single piezoelectric transducers to electronic beam manipulation using many individual piezoelectric elements in one transducer housing. This allows for complex manipulations of wave fronts. Ultrasonic phased array technology has been rather scarce in the last decade. Undoubtedly this has been due to a lack of computing power that is required for rapid excitation of the multi element transducers and the need to process large data files these scans produce. Phased array technology is the ability to electronically modify acoustic wave characteristics such as beam angle, and focusing. Probe modifications are performed by introducing time shifts in the signals sent to and received from individual elements of a probe array. Any ultrasonic techniques for flaw detection and sizing can be applied using phased-array probes. This technology has made major advancements with respect to weld scanning, corrosion scanning, and difficult to inspect materials. Phased array provides high speed electronic scanning without moving parts, improved inspection capabilities through software control of beam characteristics, and inspection with multiple angles with a single probe.Adobe Illustrator 24.1 (Windows) iLovePDF
