Ultrasonic total focusing method for internal defects in composite insulators
Insight - Non-Destructive Testing and Condition MonitoringIn order to address the problem of poor imaging detection of internal defects caused by the multi-layer curved surface structure and strongly attenuating material of composite insulators, the total focusing method (TFM) with two-layer curved surface correction was investigated.

Ultrasonic Inspection of Weld Defects Using Total Focusing Method
Lecture Notes in Mechanical Engineering, 2021Ultrasonic arrays have been widely employed in industrial applications because of their ability to perform quick inspections for detection and characterization of flaws. The total focusing method (TFM) is an advanced ultrasonic imaging technique that utilizes the full matrix capture (FMC) data of the phased array elements to generate a high-resolution ...

Multiwave Total Focusing Method for Full-Matrix Imaging Using Ultrasonic Phased Array
Materials Evaluation, 2021The imaging range of the traditional total focusing method (TFM) is usually limited by the directivity of excitation of a single wave pattern. In this paper, a multiwave TFM technique is proposed, which uses both compression and shear vertical (SV) waves for detection and imaging simultaneously.

Insight - Non-Destructive Testing and Condition Monitoring, 2023
Ultrasonic testing of coarse-grained materials is strongly influenced by high-level scattering noise. In addition, the signalto-noise ratio (SNR) and spatial resolution of imaging by the traditional total focusing method (TFM) are relatively low. In this
