Abstract
The availability of ultra-high speed imaging equipment capable of frame rates up to 1 GHz has opened the potential for measurement of full-field three-dimensional deformation data during highly dynamic events by employing the digital image correlation method. However, due to the characteristics of ultra-high speed cameras as well as experimental conditions during ballistic events, the application of digital image correlation is not straightforward. We propose to develop novel image correlation algorithms and data pre- and post-processing technologies that address these issues and utilize the image data from ultra-high speed sensors to its optimal potential. Furthermore, we propose to develop an improved ultra-high speed image sensor that can provide greatly reduced bias in practical applications as well as enhanced light sensitivity. These developments will ultimately result in a full-field deformation measurement system capable of acquiring data at rates of 1 GHz with an accuracy comparable to current quasi-static stereo image correlation systems.
