A system and method for full-field pulse-echo laser ultrasonic propagation imaging is provided. The full-field ultrasonic propagation imaging system generates ultrasounds on a structure by scanning the structure and emitting laser beams, simultaneously senses ultrasounds propagated through thickness of the structure, and generates a through-the-thickness ultrasonic propagation image. Accordingly, the full-field pulse-echo laser ultrasonic propagation imaging can visualize information on through-the-thickness defects in a full field.
