We have created the setup for determination 3D surface displacements and deformations by combined technique when out-of-plane deformations were measured by the phase shifting speckle interferometer and in-plane deformations - by using the interferometer object wave the digital speckle correlator (DSC) using only the interferometer object wave. The phase-shifting interferometer is based on scheme for z-component determination by one step phase shift of reference wave on arbitrary unknown angle. The procedure for out-of-plane deformation determination...
