On the theory of space-time polarization holography

Polarization holographic recording and the reconstruction of the field of a nonstationary object wave are considered theoretically. Expressions for the nondiffracted beam, as well as the virtual and real images, formed by a space-time polarization hologram are analyzed. It is shown that, under certain conditions imposed on the isotropic, anisotropic, and gyrotropic responses of a polarization-sensitive medium, one can adequately reconstruct the space structure, time waveform, and polarization characteristics of the field of a nonstationary object in the virtual image.
