Dynamic fringe pattern can be observed throughout the testing by real-timeholographicinterferometry, while the traditional method is only suitable for static fringe pattern in phase extracting.
This paper presents the successful use of multiple holographicinterferometry in realizing the holographicrealtime double exposure (time average) interferometry.
