  • Method of using a microscopic digital imaging strain gauge
    Patent number: 6189386
    Abstract: A method of using a microscopic digital imaging strain gauge includes the steps of creating a mark pattern on an object surface, positioning an image sensing device over the mark pattern, magnifying the mark pattern with a magnification lens, taking a first magnified image of the mark pattern with the image sensing device, applying a load to the object surface, taking a second magnified image of the mark pattern, and utilizing a processor to calculate the strain as derived from the first and second magnified images.
