摘要： An ultrasonic transducer using a piezoelectric composite in which a plurality of piezoelectric poles are arranged in matrix maintaining a gap and a polymer is charged into the gap. The piezoelectric poles are arranged maintaining a pitch which is shorter than a wavelength of a sound wave at a fundamental resonance frequency of the transducer in a medium. Further the pitch may be changed in a direction in which the piezoelectric poles are arranged, in order to restrain the grating lobe from generating.

摘要： A multi-element ultrasonic transducer in which elements are arrayed and in which a plate-shaped piezoelectric material has its one face formed with a uniform electrode and its other face formed alternately with electrodes corresponding to the respective elements and electrodes for separating the elements. These electrodes for the element separation are connected the uniform electrode opposed thereto and is fed with a ground potential. On the other hand, the electrodes corresponding to the respective elements are fed individually with transmitting and receiving signals independently of the elements so that the electronic scanning or focusing operations can be achieved.

摘要： An acoustic microscope comprising an acoustic transducer which performs both generation and detection of acoustic wave beams, and a sample holding member which opposes to an acoustic wave transmitting and receiving surface of the transducer, to hold an object sample through an acoustic wave propagating medium and to offer behind the sample a layer of an acoustic impedance unequal to that of the sample, so that the sample holding member is moved in parallel, thereby to detect acoustic waves reflected from front and rear surfaces of the sample and acoustic waves reflected from a surface of the sample holding member without reaching the sample and to measure amplitudes and returning periods of time of the reflected acoustic waves, so as to measure the velocity of sound through the sample of unknown thickness, the acoustic impedance of the sample, etc. from the measured values.
