Ultrasonic Imaging of Cylindrical Explosive Loads
Abstract
Acoustic holography has been used successfully to image a simulant of the explosive PBXW106. Flaws less than 1/8 inch can be detected in glass bead simulants which are 1/2 inch in thickness, using a frequency of 1 MHz at 300 watts peak power. With these results, calculations were made which show the explosive can be imaged. Flaws and density differences in the explosive can be determined at or near this same frequency. An outline of a total, automated inspection system is given with detailed descriptions of the linear receiving array and the sonifying phased array. The liquid surface system currently being used for a research tool is also described.
