Linear Phase Shift Response with High Dynamic Range for Holographic Recording in As2S3

High dynamic range imaging for archaeological recording

Recording media that exhibit high dynamic range for digital holographic data storage.

A general strategy for fabricating thick, optically flat photopolymer recording media with high dynamic range (M/#) that exhibit low levels of recording-induced Bragg detuning for holographic data storage is presented. In particular, media with M/# values as high as 42 in 1-mm-thick formats are obtained. We believe that these results are the first demonstration of a holographic storage medium w...

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...

A Novel Metamaterial Microelectromechanical Systems Phase Shifter with High Phase Shift and High Bandwidth

In this paper, new topology of phase shifter is proposed that uses advantage of metamaterial and MEMS technology. The phase shifter is switched between two states of RH- and LH-TL having frequency passband unlike other proposed metamaterials which create the maximum phase shift from one unitcell. Analysis and design approach of the phase shifter is presented and the structure is simulated using...

Global optimization of sensitivity and dynamic range for two-center holographic recording

The performance of two-center holographic recording is theoretically studied and described in detail. We present a systematic method for global optimization of two-center holographic recording. Whereas the method presented is general, we perform optimization for lithium niobate crystals doped with iron and manganese (LiNbO3 :Fe:Mn). Both dynamic range (M/#) and sensitivity (S) are considered fo...
