New recording material with AgBr nanoparticles for optical holography

New recording materials for holography

Some of the alternative silver halide materials that can be considered to replace the previous Agfa Holotest materials are discussed. The characteristics of Slavich and HRT materials are examined, including the special aspects of recording and processing ultrahigh-resolution silver halide materials. These materials can offer a significant improvement in product quality. The sensitivity is lower...

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...

development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles

a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...

Synthesis of a new Diarylethene for Optical Recording

Synthetic optical holography with nonlinear-phase reference.

Synthetic optical holography (SOH) provides efficient encoding of the complex optical signal, both amplitude and phase, for scanning imaging methods. Prior demonstrations have synthesized reference fields with a plane-wave-like linear variation of the phase with position. To record large images without probe-mirror synchronization, a long-travel, closed-loop reference mirror stage has been requ...
