Abstract
We designed a 1D ultrasonic array for phased array applications based on the lateral micromachined ultrasonic transducers (L-CMUT), which are in-house designed and manufactured at the Fraunhofer IPMS. The 1D array is a pretest for a 2D configuration, which would allow beam steering in 2 dimensions. The functionality of the 1D array and its control electronics have been tested and verified. Steering of the beam is possible in 0.33° steps in a range of ±30° before the amplitude decreases up to a maximum angle of ±60°. To characterize the sound field, a setup utilizing an industrial cobot equipped with a reference microphone has been realized. To test the imaging capabilities different objects have been placed up to 1 m in front of the phased array. The measurement system can be used to detect the distance and position of an object relative to the position of the phased array.
