Abstract:
Progress on ultrasonic delay line research is discussed. The results of a continued study of lead as a bonding and backing material for ultrasonic delay lines are presented. The tripletravel response level was reduced below the level of spurious responses due to diffraction for a majority of delay line applications. The results of an investigation of the diffraction field, in a solid medium, of an ultrasonic transducer are presented. The experimental results indicated that the assumptions made in the mathematical description of acoustic diffraction phenomena are valid. Design techniques for polygonal delay lines are discussed in terms of spurious response levels. A theoretical analysis, based on Fresnel diffraction theory, is presented, which results in the determination of the optimum transducer length for minimum spurious response level. Author
