Continuous laser generation of ultrasound
 
Caron, Maryland, developed a laser-based generation of ultrasound.  In conventional laser-based ultrasound, a pulse of light is incident on a solid.  The light is converted to heat expanding the material near the surface.  This thermoelastic expansion creates an acoustic wave in the material.  Detection of the ultrasound allows the nondestructive inspection of the material.  The rate of performing an ultrasound scan is inherently limited by the pulse rate of the laser.  In this invention, a continuous wave (cw) high-power laser sweeps across the material, using thermoelastic expansion to create an ultrasound wavefront on the surface of and in the material.  Detection of the ultrasound wavefront provides evidence of the strength of the material and the presence of defects.  With Continuous Laser Generation of Ultrasound, material analysts will be able to perform ultrasound scans potentially hundreds of times faster than the current methods.
