The field of the hologram becomes an additional register, on which a reconstructed
speckle-structure and formed by the object speckle-structure are registered.
An advantage of this method is the enhancement of the possibilities at the expense
of measuring value and direction of fast-changing deformations and vibrations,
changes of value and direction of velocity of movement of separate parts of the
object under study or its movement on the whole, enlargement of the range of the
measured deformations, deformations of the object with a varying surface microstructure, determination of degree of roughness of an object and mostly at the expense of
