This paper proposes a new method to design an optically-fabricated holographic element, where the construction optical system and the playback system can be optimized jointly. The method was driven by the use of a new holographic recording material – the photo-thermo-refractive (PTR) glass that can only be written at 325nm, while its playback takes place in the visible part of the spectrum. App...

We overview an approach to providing automated three-dimensional (3D) sensing and recognition of biological micro/nanoorganisms integrating Gabor digital holographic microscopy and statistical sampling methods. For 3D data acquisition of biological specimens, a coherent beam propagates through the specimen and its transversely and longitudinally magnified diffraction pattern observed by the mic...

A holographic Stokesmeter has the potential to be useful in high-speed polarization imaging applications. Highly polarization-sensitive gratings are an important component in a robust holographic Stokesmeter. We demonstrate a set of individual holographic gratings in a thick substrate displaying a high contrast in diffraction efficiency as a function of the polarization of the read beam. We con...

Two-wavelength holographic recording in thick phenanthrenequinone-doped poly(methyl methacrylate) photopolymer is demonstrated. By using 325 nm laser as a gating illumination during the holographic recording with 647 nm laser, a volume hologram with diffraction efficiency of ∼4% can be recorded in a 2 mm thick sample. In addition, the Bragg selectivity curve with clear sinc nulls is demonstrate...

We have developed a real-time, dynamic holographic material that exhibits rapid colouration upon irradiation with UV light and successive fast thermal bleaching within tens of milliseconds at room temperature. Photochromic polymer films were prepared by a simple solution-casting method from the benzene solution of the mixture of the photochromic molecule, poly(ethyl acrylate), and poly(phenoxye...

The holographic RG flow in AdS/CFT correspondence naturally defines a holographic scheme in which the central charge c and the beta function are related by the formula ċ = −2cβaβbG, where Gab is the metric of the kinetic term of the supergravity scalars. In particular, the metric in the space of couplings is fab = 2cGab. We perform some checks of that result and we compare it with the quantum f...

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...

The holographic renormalization group (RG) is reviewed in a self-contained manner. The holographic RG is based on the idea that the radial coordinate of a space-time with asymptotically AdS geometry can be identified with the RG flow parameter of the boundary field theory. After briefly discussing basic aspects of the AdS/CFT correspondence, we explain how the notion of the holographic RG comes...

A holographic theory on N is described by a holographic dual theory on the boundary of N with action S, an integral over the boundary of N . Thus, in the limit of a vanishing boundary, the action of the holographic dual is S = 0, the action of a topological field theory. So, if general relativity is holographic, then when formulated on M a manifold without boundary it must be topological. In th...

The paradigm of quantum physics enables us to broaden our holistic worldview, and explain and include phenomena that have hitherto been ignored or denied, which can lead to profound change in any field and in our society at large. The aim of this paper is to present quantum-holographic framework for understanding consciousness and acupuncture system, with significant psychosomatic-cognitive imp...
