Use of multiple holographic interferometry in realizing the holographic real time-double exposure (time average) interferometry

The paper presents the successful use of multiple holographic interferometry in realizing the holographic real time-double exposure (time average) interferometry. Observing interference figures of the change of a standard state recorded by double-exposure (time average) and the activity fringe provided by a real-time method, the change of the standard state can be compared with that of states of different times. This holographic interferometry provides a new method for precise real-time measurement.
