Holographic-moire technique to obtain displacement components and derivatives
Abstract
The symmetrical double beam illumination technique is combined with the holographic plate rotation around an axis on its own plane and with lens holography. The method can be utilized to obtain the components of displacement in two and three dimensional bodies, or also the derivatives of the displacements.
