ABSTRACT
Optical detection of ultrasonic signals of 7.5 MHz center frequency has been carried out by heterodyne interferometry at the rough surface of an aluminum sample. The distorted wave front was reconstructed by optical phase conjugation leading to an increase of the light-gathering power of the interferometer.
