Abstract
PURPOSE: To simplify the industrial production of acoustic-wave probes by reducing vapor-deposition processes while displaying perfect shield effect by making main crystal serve as an earth lower electrode and by using electrically conductive crystal as a conductive medium.
CONSTITUTION: Glassy carbon is used as a material which has propagation loss as small as that of quartz glass and is electically conductive. Column 110 is obtained by cutting a lump of this glassy carbon; and its one flank is optically polished and the other is given spherical concave hole 60 providing lens action. To a plate surface, piezoelectric thin film 20 such as zinc oxide is stuck direct by sputtering and on it, upper electrode 10 is vapor-deposited. Between upper electrode 10 and crystal 110 as a lower electrode, an RF electric signal is applied and an RF acoustic wave, plane wave, is radiated into crystal 110, so that it will focus on fixed focal point F. Thus, the perfect shield effect is displayed and vapor-deposition processes are reduced to simplify the industrial production of acoustic-wave probes.
