Abstract
The polarization properties of reflection Denisyuk holograms produced in a photo-anisotropic gyrotropic material by an unpolarized coherent light source are studied experimentally. The polarization state of the reconstructed image is found to depend on the polarization of the reproducing beam (polarization holographic memory). This effect is examined theoretically. Under certain limiting conditions on isotropic, anisotropic, and gyrotropic reactions of a polarization sensitive medium, the recovered image can be adequate with respect to the state and degree of polarization. When unpolarized light is used, the Jones matrix of the hologram responsible for the reconstructed image is equal to the Jones matrix of the object itself to within a constant factor; that is, illuminating the hologram with a wave of specified polarization yields a reconstructed field of the object that is identical, in terms of polarization, to the field of the object illuminated a priori with this wave. This method has been used to reproduce the degree of polarization of a partially polarized wave field and to study the polarization holographic characteristics of a photoanisotropic gyrotropic material.
