在目前的工作中,一个模块化和低成本的基于FPGA的相控阵系统的开发,使用换能器发射在40 kHz的小物体(≤ 4 mm)的声悬浮。该系统由驱动板、各种布局的换能器阵列和MATLAB®开发的软件组成。该软件可用于模拟声场、计算声阱以及通过提供的USB-SPI接口控制驱动板。该驱动器板可同时控制多达100个通道,方波信号高达20 Vpp,相位分辨率为π/1024,幅度分辨率为10位。多个相控阵可以通过提供的I2C接口连接,以增加可用通道的数量。该系统的功能是通过使用一个平面40 kHz的换能器阵列的小物体的悬浮证明。
In the present work, a modular and low-cost FPGA-based phased array system was developed that uses transducers emitting at 40 kHz for the acoustic levitation of small objects (≤ 4 mm). The system consists of a driver board, transducer arrays with various layouts, and software developed in MATLAB®. The software can be used to simulate the acoustic field, calculate acoustic traps, and control the driver board via a provided USB-SPI interface. The driver board controls up to 100 channels simultaneously with square-wave signals up to 20 Vpp with π/1024 phase resolution and 10 bit amplitude resolution. Several phased arrays can be linked via a provided I2C interface to increase the number of available channels. The functionality of the system is demonstrated by the levitation of small objects using a flat 40 kHz transducer array.
