Abstract :
This paper describes a multi-FPGA architecture dedicated for the real-time imaging using the Total Focusing Method (TFM) and an advanced acquisition technique called the Full Matrix Capture (FMC). The maximum operating frequency is 147.3 MHz for the control blocks and 161.3 MHz for the acquisition blocks. The architecture is able to perform real-time image reconstruction at a maximum frame rate of 73 fps and a maximum resolution of 128 × 128 pixels, which is adequate as a performance for a real-time imaging system with a good characterization of defects.
