Holographic techniques, that can record both the phase and amplitude of the light reflected by an object, can be used to generate a true three-dimensional image. Holograms were originally demonstrated by Dennis Gabor in the late 1940s, but significant interest and application of holography did not occur until the 1960s when a convenient source of radiation, in the form of laser, became available. During the past three decades, several types of interferometric holography have been demonstrated, each having advantages of specific devices for measurements. The technique has been used in applications that include the inspection of aircraft components, the measurement of shrinkage in concrete structures, etc. In each case, a holographic interferometer can show dimensional changes that are difficult to detect with the help of other kinds of techniques. Several types of holographic devices are used for research and quality control, the holograms being produced by a number of different methods. Контрольная работа № 2 |
