Abstract

Developed an acoustic imaging system applied in acoustic test. The acoustic array is made up of 260 MEMS microphones and control by a FPGA, which also in charge of transferring data by optical fiber. The mainframe is control by a FPGA. A DSP is in charge of processing the data from acoustic array. Two embedded system work for saving data and displaying acoustic image. Test results verified that the system can satisfy the need of acoustic imaging for machinery noise and gas-leakage noise in normal workshop. This system has a wide application.
