A new technique of processing the image data for accurately determining the object distance from the image plane, when a planar object is illuminated by a plane acoustic wave, is presented in this paper. Typical illustrations are presented, which establish the validity of the proposed technique. © 1986, Acoustical Society of America. All rights reserved.
