Title: Ultrasonic probe
Inventor: SHINOMURA RIYUUICHI
IPC: G10K11/34
Filed: 1984-03-12
Abstract: PURPOSE:To lower drive voltage and current while obtaining good sensitivity, by laminating n-stages of piezoelectric bodies performing thickness vibration of lambda/2 through insulating layers so as to align polarization direction. CONSTITUTION:Three layers of piezoelectric layers 2a-2c each having a thickness of lambda/2 and transmission switches T3, T2, T1 are successively turned ON. By setting this phase delay to a time required in propagating a longitudinal wave through one element, the excitations of the layers are intensified mutually to obtain three times of transmission sensitivity. At the time of receiving, an echo is converted to voltage by the piezoelectric body layer 2a and the transmitted wave is converted to voltage by the piezoelectric body layer 2b and furthur converted to voltage by the piezoelectric body layer 2c. All of receiving switches R1-R3 are turned ON at the time of receiving and the signal passed through the switch R2 is delayed by a half cycle while the signal passed through the switch R1 is delayed by one cycle and both delayed signals are added to improve apparent conversion efficiency.
