|Title:||Ultrasonic Research in the NIST Manufacturing Engineering Laboratory|
|Published:||January 01, 2000|
|Abstract:||The Ultrasonics Standards Group in the Manufacturing Engineering Laboratory of the National Institute of Standards and Technology ( NIST) performs research, develops standards, and offers calibration services in support of United States industry. In this paper, two areas of recent experimental research using a thin film piezoelectric polymer are briefly reviewed. One is the development and application of a large aperture lensless line-focus transducer for time-resolved pulsed-wave measurements. The second is the effect of nonlinear wave propagation on pulsed waveforms in industrial ultrasonic nondestructive testing applications.|
