Diffraction characteristics of a linear polarization hologram in coaxial recording.

Diffraction characteristics of polarization holograms have important research significance and application prospects. In this paper, the Tensor theory was used to investigate the diffraction characteristics of a linear polarization hologram in a coaxial recording. The results show that, when the signal and reference waves are coaxial aligned, the sum of the polarized direction angles of two waves in the reconstruction process is equal to the sum of these in the recording process under the condition that, the gratings of recorded intensity response and the polarization response are in balance. The study on the diffraction characteristics of linear polarization holograms based on the Tensor theory in the coaxial recording may help us with a deeper insight into the polarization holography theory. Again, our results helped in the use of a proper design for the polarizer to change the polarization direction of the incident linear polarization waves.
