Abstract
In this paper we have studied the recording of Fourier holograms in a PVA-AA photopolymer, analysing the influence of beam ratio in the quality of the reconstructed images. As a result, it has been observed that the variation of the beam ratio produces significant changes in the response of the material, showing that there is a range of optimal values that gives the best performance of the photopolymer for the recording of Fourier holograms. Effects on edge enhancement as consequence of spatial filtering on the reconstruction stage has been observed for low values of beam ratio. The best beam ratio obtained from this study has been used for holographic multiplexing of four Fourier holograms.
