Holographic data storage: science fiction or science fact?

17‐2: Shearing Bragg Gratings for Slim Mixed Reality

“…Switching force scales with the inverse of film thickness so could easily be reduced by using thicker film and >1 mm thick films have been demonstrated [19]. It may also be possible to reduce material stiffness, for example ultra-violet holograms can be recorded in a mixture of polysilicone and benzophenone [20] and the stiffness of polysilicone can reduce to a few kiloPascals [21].…”

Optical memory system based on incoherent recorder and coherent reader of multiplexed computer generated one-dimensional Fourier transform holograms

“…Many reports were published in the last several decades in the field of holographic memory development. The appearance and advancement of classical two-beams holographic schemes [4][5][6][7][8][9] and development of a new approaches such as collinear scheme [10][11][12] promise the possibility of practical realization of holographic memory systems. However high price of data recorders with complex and high precision optical schemes embedded inside is still cornerstone problem in this field.…”

Multiplexed holograms recorded in a low toxicity Biophotopol photopolymer

“…Recently, the Biophotopol photopolymer capability as a data recording material has been demonstrated using two different peristrophic multiplexing techniques 1 . These techniques are commonly used in holographic data storage experiments [2][3][4] . Peristrophic multiplexing is a very useful tool especially when the holographic recording medium is relatively thin.…”
