Description

Acoustic images offer good spatial resolution in two dimensions, but do not give information on the third spatial dimension. In this paper we will describe a new method of measuring flaw depth profiles which makes use of the corner reflections from a surface breaking flaw. A calibration experiment is described, showing that at the present time this method of flaw depth determination can be calibrated to an accuracy of about 20%.

Determination of Flaw Depth Profiles from Acoustic Images

La Jolla, CA

Acoustic images offer good spatial resolution in two dimensions, but do not give information on the third spatial dimension. In this paper we will describe a new method of measuring flaw depth profiles which makes use of the corner reflections from a surface breaking flaw. A calibration experiment is described, showing that at the present time this method of flaw depth determination can be calibrated to an accuracy of about 20%.
