1 Next Generation Phased Array UT Total Focusing Method (TFM) Gavin Dao and Alan Caulder AOS, Cincinnati, OH Dominique Braconnier and John Lorenz TPAC, West Chester, OH

2 Introduction Preview of Advanced Imaging What is Full-Matrix Capture (FMC)? What is Total Focusing Method (TFM)? Standard TFM Migration Advanced FMC / TFM Adaptive TFM Images About AOS OEM-PA

3 Conventional Phased Array UT Phased Array Linear Scan 3

4 FMC/TFM 4

5 Conventional PA vs FMC/TFM FMC/TFM Conventional Phased Array

6 FMC/TFM: Some Benefits Beautiful Image! Like a drawing of the test piece Provides better perspective Vertical Resolution Improved See next video Lateral Resolution Improved 3 holes: Can see the small nuance of 3 mm center to center and 4 mm center to center Can see that the SDHs are 1 mm in diameter. Understand images a lot easier Able to differentiate what is a real defect vs geometry echoes 6

11 Software Develop Your Own Software OR Use 3 rd Party Supported Software AOS Provides Software Development Kit (SDK) Dynamic Link Libraries (DLL) Application Programming Interface (API) Full control of Phased Array Parameters Receive each A-scan in a buffer that can be interfaced to your own software Full Documentation Set Customize: Create a simple dedicated application. Don t get stuck with an overly complex software where you only use 5% of the features

12 Full-Matrix Capture (FMC) Pulse Pattern Cycle 1 Cycle 2 Cycle 3 Cycle 4 Receive Pattern In this example, we have 4 elements 4 x 4 = 16 Raw A-scans
