Simulation on qualitative detection of defects with multi-mode total focusing method
2018 IEEE Far East NDT New Technology & Application Forum (FENDT), 2018Multi-mode total focusing method (TFM) is applied to overcome the limitation that defect type is difficult to be accurately determined with conventional ultrasonic testing. The phased array transducer connected with wedge is employed to implement electronic scan and receive the multiple reflected waves generated from defect surface.

Dijkstra’s algorithm-based ray tracing method for total focusing method imaging of CFRP laminates
Composite Structures, 2019Abstract Accurate determination of ultrasonic travel time from a start point to an end point with known positions is fundamental to the application of total focusing method (TFM) to ultrasonic array imaging. However, this is particularly challenging for CFRP laminates whose wave propagation is complex due to material anisotropy and refractive ply ...

Total focusing method for non destructive evaluation: Toward real-time imaging systems
2013 IEEE 56th International Midwest Symposium on Circuits and Systems (MWSCAS), 2013This paper describes a dedicated architecture for real-time imaging using the Total Focusing Method (TFM) and an advanced acquisition technique called the Full Matrix Capture (FMC). The architecture was entirely described using VHDL language and implemented on a V5FX70T Xilinx FPGA for the control part and a V5SX95T Xilinx FPGA for the acquisition part.

In this paper, we propose an ultrasonic adaptive imaging method based on the phased-array technology and the synthetic focusing algorithm Total Focusing Method (TFM). The general principle is to image the surface by applying the TFM algorithm in a semi-infinite water medium.
