Résumé
The PVA/Acrylamide photopolymers are materials that are used for holographic grating storage. In this work, a combination of two multiplexing methods - peristrophic and angular multiplexing - is used to record 60 holograms. An exposure schedule method will be used to optimize the capability of the photopolymerizable holographic material and obtain holograms with a higher, more uniform diffraction efficiency. In addition, thanks to this exposure schedule method, the entire dynamic range of the material will be exploited, obtaining values of approximately M# = 9 in layers about 800 μm thick.
