Abstract:

Increasing the size of transducer array can improve the accuracy of focusing， but it also brings the increase of power consumption and focusing noise. To solve this problem， a local ultrasound array focusing method based on multi array synthetic aperture was proposed.The number of focused transducer was determined by proposed method according to the radiation angle of transducer， and power consumption and noise were reduced by reducing the number of transducer working at the same time. The focusing accuracy and power consumption of local array focusing method and full array focusing method are tested. The results show that， compared with the full array focusing method， the focusing accuracy of the proposed method is slightly improved， the focusing intensity is reduced by 5%， but the power consumption is reduced by 31%.

Key words: communication and information system, aerial tactile, ultrasound tactile, ultrasound transducer array
