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 in the reconstruction process, is presented, and its usefulness is shown by experiments.
