Microvec Digital Image Correlation (DIC) System

Microvec offers a combination of advanced integrated hardware and software to create a wide range of Digital Image Correlation systems for many different applications. Microvec DIC can consist of one camera for 2D, two cameras for 3D as well as a high speed camera for high speed DIC analysis.

Digital Image Correlation (DIC) is an optical method of tracking the movement of the naturally occurring, or applied surface pattern during the test or experiment. DIC uses accurate 2D and 3D measurements of changes in image to measure contour, deformation, vibration and strain on almost any material. The maximum correlation in each window corresponds to the displacement, and this gives the vector length and direction for each window. MicroVec uses algorithms use multi-pass multi-grid processing and window deformation for the highest accuracy of measurements. With use of GPU and use of parallel processing, Microvec DIC software can perform the calculations in near real-time.

The MicroVec DIC systems are integrated from world leading CCD cameras from Imperx (USA) or any numbers of CMOS high speed cameras from USA or Japan. All systems are sold as complete solutions, with a multitude of possible configurations depending on selected cameras, lenses, lights and rail sizes. The selection of the right system can be

Microvec DIC systems are used in number of applications from geology to material research and from microscopic areas to large structures.
