Abstract

The subject of holographic interferometry encompases construction, observation, and interpretation of interference patterns of waves of which at least one has been recorded on and reconstructed by a hologram. The principle of holographic interferometry is illustrated by Fig. 1.1 which displays a general arrangement for obtaining a hologram and reconstructing the wave recorded in it. As has been shown earlier, the interaction of the reconstructing wave with the pattern recorded in the hologram (Fig. 1.1b) results in a reconstruction of the object wave. If the reconstructing wave is an exact copy of the reference wave, then both phase and amplitude of the object wave will be faithfully reproduced. If we illuminate the hologram after removing the object, we will see the object image at the exact place and in the same state it occupied during hologram recording. If the object is not removed, then two waves will propagate simultaneously behind the hologram, namely, the wave reconstructed by the hologram, and another one diffracted directly by the object. These waves are coherent and can thus interfere; the interference pattern characterizes the changes which have occurred in the object in the time between hologram recording and observation of the interference pattern. If the state of the object has changed during the observation, for instance, as a result of a deformation or displacement, the interference pattern will have changed, too.
