The present invention discloses a method and system for laser ultrasonic imaging an object. In the present invention, a synthetic aperture focusing technique (SAFT) is used to generate a high resolution subsurface images of the object. In addition, the present invention filters low frequency components from detected laser ultrasound waveform data to further enhance resolution, SNR, and contrast. Geometric knowledge permits the present invention to generate images of objects having a complex and arbitrary-shape.
