Laser Ultrasonics

Laser ultrasonics uses extremely high-speed, low-power pulsed laser bursts as a nondestructive, high-precision sensing tools for measuring the properties of materials like paper, sheet metal, glass, and rolled plastics.

In the first application of laser ultrasonics developed in the Advanced Energy Technologies Department, an LUS sensor is being used to measure nondestructively the quality (bending stiffness and shear stiffness) of paper at a mill in real time. The sensor could save the paper industry hundreds of millions of dollars in energy costs and discarded fiber material each year. This technology is an R&D 100 award winner.
