Abstract

We describe a system that has enabled non-harmonic deformations to be measured with microsecond(s) temporal resolution for the first time with speckle pattern interferometry. The short exposure period and high framing rate of a high-speed camera at up to 40,500 frames per second allow low-power CW laser illumination and fiber-optic beam delivery to be used. The technique has been demonstrated in the laboratory and tested in preliminary industrial trials. The ability to measure vibration with high spatial and temporal resolution, which is not provided by techniques such as scanning laser vibrometry, has many applications in manufacturing design.
