Abstract
The bands and corners of rectangular or other geometric shapes for binary code symbols are used to measure non-linear and non-uniform strain in a material with an anomaly such as a crack in the area of strain measurement. In particular, they can be used to evaluate differential strains in the regions of the bands and corners; and the external and internal boundaries can be used to measure differentials in strain between the external boundaries and internal boundaries.
