Instantaneous Phase Coherence Imaging for Near-Field Defects by Ultrasonic Phased Array Inspection
This paper describes an imaging method for near-field defect detection in aluminum plates based on Green’s function recovery and application of instantaneous phase coherence weighting factors. The directly acquired acoustic information of near-field defects is usually obscured by the nonli...
