Abstract :
[en] In Chapter 6, Marc Georges presents the holographic interferometry technique. This technique allows the measurement of the phase of an object or a scene, which evolves over time, and is used to detect defects in laminated material. It can also be used for measuring the vibration modes of industrial components such as turbine blades. After defining the characteristics of an ideal system, Georges reviews the different implementations that have been proposed, moving from analog systems to the more modern electronic speckle pattern interferometry. Because the sensor resolution keeps improving, it is now possible to detect the interference fringes directly, which leads to the most recent digital holographic interferometry techniques, which are described at the end of the chapter.
