A material-parameter-driven velocity-corrected phase-coherence fusion algorithm for total focusing imaging of CFRP defects

Conventional ultrasonic total focusing method (TFM) imaging of carbon fiber reinforced polymer (CFRP) laminates is limited by anisotropic propagation-time mismatch and structural noise, which impair the detection and localization of small, deeply buried defects. Existing velocity-corrected phase-coherence methods often...
