Abstract
A strain gauge includes an image sensing device having a lens, a magnification lens optically coupled to the lens, a positioning mechanism connected to the image sensing device, an image capture device for receiving an image from the image sensing device, and a processor for mathematically analyzing the image received from the image capture device and to calculate strain.
