“…It has been previously shown [12][13][14][15][16][17][18][19][20][21][22] that the holographic recording process in nanoparticle doped photopolymerisable materials can lead to the redistribution of the nanoparticles and thus to the creation of patterns of particle rich and particle depleted areas ( Figure 1B). The diffraction efficiency, η, of such a volume phase hologram is given by (2):…”

“…The basic idea behind the concept of the photopolymerizable nanocomposites is to introduce nano-dopants with significantly different refractive index from that of the host material and to achieve redistribution of the nano-dopants during holographic recording. [12][13][14][15][16][17] It has been shown that optimum values of recording intensity and volume fractions of incorporated solid nanoparticles such as SiO 2 18 , TiO 2 19 and ZrO 2 20 , lead to an increase of diffraction efficiency of the recorded gratings due to a higher refractive index modulation.…”

The optical properties of photopolymer layers consisting of an acrylamide-based matrix and microporous aluminophosphate nanocrystals of AEI-type are investigated. The compatibility of the photopolymer doped with the nanoparticles is studied. The surface and volume properties of the layers with different levels of doping with microporous nanocrystals are characterized. The effective refractive indices and absorption coefficients of the doped photopolymer layers are determined and used to calculate the refractive index and porosity of pure AEI nanoparticles used as dopants. Volume transmission gratings were recorded in the doped photopolymer layers at different spatial frequencies.By spatial monitoring of the characteristic Raman peak of the AEI particles across the grating vector, the optimal concentrations of the nanocrystals for obtaining highest light induced redistribution of nanocrystals are determined. The optical properties of the photopolymer layers combined with the redistribution of the AEI nanoparticles during holographic recording are the parameters exploited for fabrication of optical sensors. An irreversible humidity sensor based on a transmission holographic grating is designed and fabricated. The diffraction efficiency of the sensor changes permanently after exposure to high humidity.

“…Inorganic nanoparticles embedded in a photopolymer matrix (nanoparticle-polymer composites) have already been investigated intensively [12][13][14] for light-optics applications. In nanoparticle-polymer gratings, the refractive-index modulation amplitude Dn for neutrons can be tuned by choosing a suitable value of b c , i.e., the species of nanoparticles.…”

We report on successful tests of holographically arranged grating-structures in nanoparticle-polymer composites in the form of 100 microns thin free-standing films, i.e. without sample containers or covers that could cause unwanted absorption/incoherent scattering of very-cold neutrons. Despite their large diameter of 2 cm, the flexible materials are of high optical quality and yield mirror-like reflectivity of about 90% for neutrons of 4.1 nm wavelength.

“…For instance, 13 nm silica nanoparticles were added to the methacrylate photopolymers by Suzuki et al, and a noticeable reduction of scattering loss and a high-contrast refractive-index change were achieved [59]. A gold-nanoparticle-doped photopolymer was used to suppress side lobes of angle selectivity of volume holographic gratings by Cao et al, achieving a higher diffraction efficiency [60,61].…”

Abstract:The synthetic holographic stereogram printing technique can achieve a three-dimensional (3D) display of a scene. The development and research status of the synthetic holographic stereogram printing technique is introduced in this paper. We propose a two-step method, an infinite viewpoint camera method, a single-step Lippmann method, a direct-write digital holography (DWDH) method and an effective perspective images' segmentation and mosaicking (EPISM) method. The synthetic holographic stereogram printing technique is described, including the holographic display with large format, the large field of view with no distortion, the printing efficiency, the color reproduction characteristics, the imaging quality, the diffraction efficiency, the development of a holographic recording medium, the noise reduction, and the frequency response analysis of holographic stereograms.
