Abstract
The possibility of polarization holographic recording of a standing wave in the case when the same (right or left) circularly polarized plane coherent light waves propagate in opposite directions has been discussed. The propagation of a normally incident circularly polarized wave along the helical structure formed in a photoanisotropic medium has been discussed by means of the Jones matrix method. The selective reflection of the circularly polarized component of mcident light from such a reflectance hologram is possible. When summing up two coherent light waves with different polarization states the summary field is characterized by a definite distribution both the intensity and resulting polarization. The use of photoanisotrophic media enables us to make a polarization-holographic recording of the summary field and to reconstruct polarization state of the object wave from the obtained hologram. 2 3 If we use two beams with orthogonal right and left circular polarization '' which spread at a small angle with each other the projected picture of the summary fields in the hologram plane has the form of a periodic structure corresponding to a linear polarization with orientation rotation of the resulting vector from O to 180 within the period. The absence of intensity modulation on the hologram plane leads to a uniform distribution of the values of light-induced anisotropy.
