A PROPOSED RESOLUTION TEST FOR ULTRASONIC ANGLE BEAM PROBES

RESULTS ARE PRESENTED OF A STUDY ON AND EXPERIMENTAL VERIFICATION OF A RESOLUTION TEST FOR ULTRASONIC ANGLE BEAM PROBES. A TARGET IS PROPOSED CONSISTING OF A GROUP OF THREE SMALL, IN-LINE HOLES WITH FINISHED BORE. THE INTERACTION BETWEEN THE PITCH OF THE HOLES AND THE ATTITUDE OF THE LARGEST GROUP TO THE SOUND BEAM IS SHOWN. TEST BLOCKS ARE PROPOSED THAT MAINTAIN A COMMON PROBE-TO-TARGET DISTANCE AND TAKE INTO ACCOUNT THE FREQUENCY OF THE SOUND AS WELL AS THE ATTITUDE OF THE TARGET TO THE SOUND BEAM. OTHER MODELS OF TEST BLOCKS FROM THE LITERATURE ARE COMPARED WITH THE PROPOSED BLOCKS. /AUTHOR/
