title: Distortionless recording in double-exposure holographic interferometry.
abstract: When measuring two- or three-dimensional displacements by double-exposure holographic interferometry, observing directions of the same number are necessary to determine displacement vectors. In the conventional method, identification of the corresponding points on the three interferograms requires a great effort since object images have different shapes for each observing direction. To eliminate this laborious process, a method of distortionless recording, which utilizes the real image with the fringes formed on the original object surface shown by experiments.
