Polyvinyl acetate with cellulose dinitrate holograms

A new recording material with a high diffraction efficiency of around 90% has the possibility to be applied for replication of computer phase holograms. This material is polyvinyl acetate with cellulose dinitrate, both substances are doped, and it is easy to apply for any substrate without the need for a dark room and critical conditions. This is because the absorption spectra of polyvinyl acetate with cellulose dinitrate is localized in the IR region λ = 7.43 μm. We recorded on this material by applying heat by friction pressure on the surface of a binary mask (hologram) by lithographic techniques.
