Abstract
Certain methods for measuring the shift of an object as a whole by means of holographic interferometry are briefly discussed. An attempt is made to improve these methods by introducing a test shift of the object under investigation (or a collimating lens of the reference beam) in the time interval between exposures along the optical axis. This procedure allows one to determine the direction (sign) of the shift of the investigated object in its own plane. A detailed theoretical analysis of the recording of double-exposed Fourier holograms with combined phase shift is given.
