Live demonstration: FPGA-based real-time acoustic camera prototype

Fig. 1 shows the real-time acoustic camera prototype. The system consists of a field-programmable gate array (FPGA) base-board and an A/D-conversion board with 32 attached microphone modules arranged in a rectangular array. The FPGA base-board is connected to an external TFT display. Two loudspeakers will be connected to a laptop and play audio test-signals. The external display visualizes the location and intensity of the generated sound sources in real-time. The following list summarizes the components required by this demonstration setup:
