1. A computer-implemented method for measuring full field deformation characteristics of a body, the method comprising: generating a dot pattern for application to the body by a computer processor, said generating including: determining a position of a first dot, iteratively determining a position of a next dot with a random number generator having a preset value for mean dot distance, and checking a distance between the next dot and each previous dot to reject the next dot as an overlapping dot if the distance between dots is less than twice the dot radius, and continuing to determine positions for dots until the dot pattern has a preset minimum number of dots or until a minimum number of iterations has been reached; applying the 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; matching the characteristic points between two or more subsequent images; calculating a displacement vector of the characteristic points; and calculating full field displacement based on the displacement vector of the characteristic points.
