1. A computer-implemented method for measuring full field deformation characteristics of a body, the method comprising: determining optical setup design parameters for measuring displacement and strain fields; applying a dot pattern on a planar side of a deformable body; acquiring a sequence of images of the dot pattern before and after deformation of the body; identifying the characteristic points of the dots with a computer processor; eliminating irregular objects from the sequence of images; matching the characteristic points between two or more subsequent images; calculating the displacement vector of the characteristic points; and calculating full field displacement based on the displacement vector of the characteristic points.
