摘要：

A scanning acoustic imaging system at 50 MHz using phase conjugate waves is proposed. The phase-shift-undoing property of the phase conjugation was used to remove the wavefront distortion of the sound beam. Obtained images showed the attenuation property of the samples and were free from the influence of surface roughness.
