In a unique and powerful collaboration between our facility and the Mechanical Engineering Dept at the University, we are offering a new service: Digital Volume Correlation, using the LAVision commercial software package.
The software calculates changes occurring in a sample in full 3D, making it possible to quantify and visualize changes in 3D using colour maps. A simple example is shown below of a wood block scanned at 2 microns resolution, before and after wetting, to show the regions of most expansion due to moisture absorption. Red colour indicates largest variations, correlating roughly to inter-cellular crack regions where the water penetrated easiest.

This new service requires ideally two “before” scans, and one “after” scan, of the same sample subjected to some process such as heating, wetting, drying, compression or even growth. It will only work for samples with good internal structural variations for pattern recognition. Please send mail for more information.
