A prototype ultrasonic inspection system, using a sequentially fired transducer array, has been built that is much faster than conventional single-element transducer systems. This system was assembled with off-the-shelf components and would appear to be an attractive solution to nondestructive testing problems that require fast inspection rates and have resolution and sensitivity requirements that are consistent with the use of unfocused transducer elements. The fast inspection of a number of Army components, such as artillery projectile rotating bands and tank track pads, has been demonstrated with this system. Author
