Static and dynamic volume holograms

Consideration is given to the imaging properties of intensity waves as well as to the coherent manifestations of these properties as a function of the properties of the photosensitive medium in which the holograms are recorded. Dynamic holograms, recorded in resonant media and media with the capacity for stimulated scattering, can be used to perform wave-front reversal; both the spatial and temporal characteristics of the wave fronts can be determined. In the case of static three-dimensional holograms, the sensitized photooxidation reaction makes it possible to obtain phase holograms with a high diffraction efficiency in different regions of the spectrum. The mode theory of three-dimensional holograms gives a sufficiently simple description of the interaction of radiation with the complex structure of static and dynamic three-dimensional holograms.
