Photoinitiation system for holographic recording material.

New photopolymer holographic recording material with sustainable design.

Photopolymers that absorb in the visible spectrum are useful for different applications such as in the development of holographic memories, holographic optical elements or as holographic recording media. Photopolymers have an undesirable feature, the toxicity of their components and their low environmental compatibility, particularly if we analyse the life cycle of the devices made with these m...

Optimization of a photopolymerizable material based on a photocyclic initiating system using holographic recording.

A set of photoinitiating systems (PIS) for free radical photopolymerization was studied using time-resolved spectroscopic experiments, real-time FTIR and holographic recording. It is shown that the efficiency of the photoinitiating system can be drastically increased when a redox additive is added to the conventional dye/coinitiator system by virtue of photocyclic behaviour. The homogeneous pho...

Two-center holographic recording

We describe a two-center holographic recording method for the storage of persistent holograms in doubly doped lithium niobate crystals. We use a two-center model, and we show that our experimental observations can be explained by the model. We describe experimental methods for finding the unknown material parameters of LiNbO3 :Fe:Mn crystals for the two-center model, and we discuss the optimiza...

Recent advances in holographic recording media for dynamic holographic display

An overview of the recent advances in the state-of-the-art holographic recoding media dedicated to the dynamic holography display is presented in this paper. Unlike the traditional holographic media, those materials enable the holograms to be updatable rather than permanent like before. Over the past few years, a number of material recipes for this use have been disclosed and can be mainly divi...
