The Messphysik Videoextensometer ME46 is an passive marker system that can be used for cinematic analysis and the accurate measurement of the displacement of individual markers in 2D.
In principle, the system tracks the edges of ‘black on white’ or ‘white on black’ markers by analysing the brightness contrast.
The system can be integrated to the servo-hydraulic testing machine for measurements of local displacement and strains. The field of view (FOV) size can be varied between a few mm and meters as it depends on the selected optics. (C-mount lenses). The device measures frame frequencies up to 60 Hz.
