Abstract: For the low test efficiency of the near-field acoustic holography techniques based on the multi-reference cross-spectrum method, an automatic near-field acoustic holographic scanning measurement system is designed. The system uses high-precision linear guide slider mechanism, and the lower computer uses a programmable logic controller to control the microphone array moving quickly and accurately to the preset measurement position. The embedded real-time controller and data acquisition card of NI company are used as the hardware of the data acquisition device, and the data acquisition program is written by LabVIEW, which can carry out real-time acquisition of multi-channel sound pressure data. In order to combine the two processes of microphone array movement and data acquisition and realize the automatic acquisition of sound pressure at the measuring position, the upper computer program is written based on the QT application development frame, which controls the programmable logic controller and data acquisition equipment, and completes the whole process of automatic scanning measurement. The experimental results show that the system can quickly and accurately collect the sound pressure data on the holographic plane, thus improving the testing efficiency of near-field acoustic holography.
