Digital image correlation is a full field operating optical system to measure deformation and strain on planar and non-planar surfaces under static and dynamic load. The process
distinguishes itself by simple application and insensivity to malfunctions.

In broad daylight, no laser is required for operation.

The example shows strain on the x-axis of a vibrating surface which is connected midway and point-shaped to a shaker.

Strain is color-marked and overlays  the condition of deformation. The process was carried out with the isi-vibrocorrelation system.

General infomation regarding the method of image correlation can be found here.

Image correlation is used in different measurement/testing applications.
