摘要

The Full Matrix Capture (FMC) method can provide the original complete information which is detected by the ultrasonic array and can recover with the Total Focusing Method (TFM). This technique has better detection sensitivity and resolution relative to conventional scanning method and is valuable for improving the quality and reliability of industrial non-destructive testing. However, it has low computational efficiency and cannot meet the demands for industrial real-time detection. Here, we present a new way to improve the detection efficiency of the ultrasonic FMC imaging detection based on increasing the effective aperture. Firstly, we discuss the factors which impact the effective aperture of ultrasonic array and the detection performance impacted by the aperture. Then, we present the method to effectively improve the efficiency with increasing array aperture and maintain its good detection performance. The simulation and experimental results show that the efficiency of FMC method is greatly improved.
