| Abstract: | The physical foundation of the ultrasonic waves is presented. A contactless ultrasonic sensor in seam tracing is developed. The transfer loss of the ultrasonics is reduced with acoustic impedance matching technique. The focused acoustic lens is designed, thus the diameter with 0.5mm of sonic beam is achieved. |
