Abstract
An ultrasonic C-mode imaging system incorporating an ultrasonic phase conjugator has been built and images have been obtained at a frequency of 10MHz. This system is free from the influence of wavefront distortion due to the reflection or the refraction at the rough surface of the samples and visualizes the net attenuation of ultrasonic waves.
