Abstract: This disclosure relates to a real-time video extensometer. Typically, the apparatus of the disclosure combines the image source, data processing and electrical output on to a single processing board in order to achieve high frequency images and low latency times on data flow. Further, the video processing engine processes the image on a pixel basis and updating the output the intermediate extension/strain result so that after receipt of the final image pixel, a final extension/strain value is achieved and immediately output for evaluation.

Abstract: The present disclosure provides an apparatus and method which uses a field splitter or a beam splitter for the purpose combining two different views of a materials testing sample under materials testing into a single image. This allows for three-dimensional strain measurement in the context of material/compound testing. In particular, the time and stress dependent change in gauge length can be tracked and calculated in order to calculate the time and stress dependent strain. The method and apparatus allows imaging on a single image sensor for the three-dimensional strain calculation.
