“…Note that this method is similar to the incremental recording method for photorefractive materials, proposed in Ref. 16. Therefore, this technique can be called the incremental exposure method ͑IEM͒.…”

“…Recent research has shown that PMMA doped with phenanthrenequinone ͑PQ͒ could be very attractive for volume holographic recording because it is easy to form in bulk with negligible photochemically induced dimensional change and good optical quality. 7,[13][14][15][16] In this paper, we present our experimental investigations into bulk PQ-doped PMMA. In Sec.…”

We present an experimental study on the photopolymer poly-(methyl methacrylate) doped with phenathrenequinone molecules. Material characteristics for holographic data storage, including optical characteristics, scattering effect, relation between diffraction efficiency and number of holograms, and exposure schedule for multiple storage, are investigated. An experimental demonstration of multiple storage of digital data pages in a polymer cube is presented.

“…Lin et al first proposed the kinetics of the PQ/PMMA photopolymer recording grating formation process in 1999 [ 87 ]. On the basis of dynamic measurement, they proposed two exposure schemes that realize multiple storage of equal-intensity rasters: the predetermined exposure method and the incremental exposure method.…”

Phenanthraquinone-doped polymethyl methacrylate (PQ/PMMA) photopolymers are considered to be the most promising holographic storage media due to their unique properties, such as high stability, a simple preparation process, low price, and volumetric shrinkage. This paper reviews the development process of PQ/PMMA photopolymers from inception to the present, summarizes the process, and looks at the development potential of PQ/PMMA in practical applications.

“…A strategy to deal with this can be devised in the form of an exposure schedule. Assuming a constant intensity per exposure, predetermined schedule ramps up the exposure in a slightly nonlinear fashion, so that the last exposure of 350 is four times the exposure of the first [12].…”

This article reviews the range of emulsions, photochemistry, and processing techniques that have been proposed and put into practice for the successful making of display holograms. It covers various types of media including gelatin-based emulsions and photopolymers (it focuses on the former) and considers external factors that affect the final results. This is a compact review of the history of the field but focuses on the range of easily available commercial emulsions, as well as certain accounts of how to make holographic emulsions from scratch. It considers various combinations of developer, bleach, and redeveloper, which have been used to achieve the best of various trade-offs for such factors as resolution, contrast, diffraction efficiency, clarity, color quality, blackest blacks, and resistance to printout. It describes a recent advance in hypersensitizing holographic emulsions.
