Abstract
A non-contact strain and/or displacement measurement system for use with structural objects having an optical device, a data store and an image arrangement that is fixed relative to the structural object to be tested, the optical device including an image receiving device for receiving visual images and the data store being configured to record the received visual images, the image receiving device being spaced from the image arrangement by an optical spacing such that the image receiving device has a visual range that includes a portion of the structural object and the image arrangement being within the portion, the image arrangement having at least one image element wherein movement of the at least one image element during a measurement period provides image data to calculate structural object strain and/or structural object displacement.
