Abstract
The principle of a true acoustic Gray-scale standard is presented and experimentally applied to the scanning acoustic microscope (s.a.m.). The implementation is based on the impedance-matching property of a quarter-wave impedance transformer through which precise changes in reflection coefficient may be produced in a single material. The performance of the first implementation designed for 375 MHz operation is described.Keywords
