Analysis of Ultrasonic Radiation Field Based on Linear MEMS Ultrasonic Transducer Array

Abstract:

The analysis of the acoustic field distribution characteristics for the ultrasonic transducer array plays a very important role in both the optimization of the design parameters of the array and the improvement of image quality. In this paper, the acoustic analysis method based on spatial impulse response is studied for the linear MEMS ultrasonic transducer array. The spatial impulse response for the ultrasonic transducer array and the lateral ultrasonic radiation field for the transducer array are obtained by simulation and calculation, and the simulation results are analyzed, which has important implications on the further optimization of MEMS ultrasound transducer design parameters.
