Holographic interferograms on a real time scale arise during observation of an interference image between the unperturbed image of an object recorded on a hologram and the object, observed through the hologram as it changes. The method turns out to be very convenient for rapid familiarization with the nature of deformations and vibrations of any shape, with the configuration of gas streams and so forth.
