摘要：
Non-contact ultrasound imaging system. The system includes a pulsed near infrared scanning laser source for illuminating a surface of a structure to generate ultrasonic elastic waves that propagate into the structure. A laser Doppler vibrometer measures vibration of the surface caused by the propagating ultrasonic waves in the structure and a data acquisition module processes data from the vibrometer to construct an image of the structure.
