title: Strain components obtained from contrast measurement of holographic fringe patterns.
abstract: In the study of the deformation of objects by holographical interferometry, it is possible to determine directly strain components by measurement of the contrast of the fringes. With adequate geometry and a zero method, contrast measurements give accurate values of the strain components.
