Reproduction properties of polarized hologram under Bragg mismatch condition

The reconstruction process of polarization holography needs to strictly meet the Bragg condition. This paper aims to study the Bragg condition in the reconstruction process of polarization holography. The Bragg mismatch will have a negative impact on the reconstructed recording information. It not only affects the diffraction efficiency of there constructed light in the original reference light direction, but also affects the reconstructed recording image. Based on PQ/PMMA, we studied the variation of the diffraction efficiency of the polarized hologram and its effect on there constructed recorded image under the condition of deviating from the Bragg condition.
