ULTRASONIC MEASUREMENT OF THE DIMENSIONS OF DEFECTS

MESURE PAR ULTRASONS DES DIMERSIONS DES DEFAUTS

The authors demonstrate the disadvantages of measuring defects by means of ultrasonic waves (based on the propagation of sound waves), which is normally used. Details are given of a method of focalizing ultrasonic wave beams which ensures greater accuracy. /TRRL/
