Abstract and keywords

An improved digital correlation method is presented for obtaining the full-field in-plane deformations of an object. The deformations are determined by numerically correlating a selected subset from the digitized intensity pattern of the undeformed object. The improved numerical correlation scheme is discussed in detail. The displacements of a simple object, as computed by the correlation routine, are shown to agree with theoretical calculations.

Keywords: digital; processing; displacements
