Time reversal PAUT

摘要

Currently, rapid and reliable phased array ultrasound (PAUT) inspection requires a combination of dedicated phased array probe configurations, high-performance PAUT electronics, multi-axis scanners and advanced software algorithms. Time Reversal is a real-time adaptive phased array ultrasound technique based on measurement of the front wall surface echoes and time-of-flight (TOF) compensation of the returned ultrasound data. Composite material manufacturers can now dynamically adjust for part misalignment, water column variations and surface geometry changes. This can deliver improved cost and time efficiencies on the production floor.
