A novel non-destructive testing and evaluation system based on double-pulsed, phase-sampled, laser-speckle metrology is the focus of this project. The potential of this technology is, in an industrial context, the determination of static and temporal deformation of both materials and assemblies without contact and with a resolution of spatial displacement of 0.25 m and resonance mode frequencies approaching 50,000 Hz. The method will be capable of resolving both the absolute and gradient in-plane and out-of-plane surface displacements and the dynamic and resonant behavior of objects under test.In Phase I, theoretical models and engineering designs were prepared for the development of the proposed double-pulsed, phase-sampled, laser-speckle interferometry method for non-destructive testing and evaluation.Potential Commercial Application:Areas of commercial application include the characterization of: composite delamination, vibration analysis, thin weld inspection, stress, strain, and finite-element analysis, hydraulic strain, and others. STATUS: Project Proceded to Phase II
