“…The most simple way is to TDHG reverse the obtained matrix of transparent apertures into its negative by using contact print with subsequent photochemical treatment consisting of either hardening bleaching or short-wave ultra-violet illumination action (SWUV method). [2], [3] The obtained raster includes circular microlenses with big gaps between them (Fig. 1b).…”

“…The light intensity distribution from the display image was transmitted by using the TDHG onto a light-sensitive material, a halide-silver photographic emulsion PFG-01. After development of photographic material using one of the above-mentioned techniques [2], [3] a relief image of the microlens raster was formed on the photographic emulsion, with the filling coefficient being considerably higher as compared to the one received earlier. When creating the above-considered rasters of microlenses, we have used the TDHG whose apertures were formed by routine developing and fixing of photographic emulsion.…”

A method for fabrication of a microlens raster with full filling on photographic plates PFG-01 is proposed. A twodimensional holographic crossed grating (TDHG) with improved imaging properties is used as an image multiplying optical element. In order to create the improved TDHG, we have proposed a special technique for photographic emulsion layer treatment. The light intensity distribution from the display image was projected onto a light-sensitive material using the TDHG. After the development of the photographic plates, either hardening bleaching or short-wave ultra-violet illumination is used for relief creation.Keywords: silver-halide photographic emulsion, holographic optical elements, microlens raster TWO-DIMENSIONAL CROSSED HOLOGRAPHUC GRATING FOR RASTER IMAGE CREATIONWe have previously considered the two-dimensional crossed holographic grating as an optical element having the ability to create raster images. [1] The 2-D crossed grating can be easily obtained by double recording an interference pattern of two plane waves propagating at a certain angle to each other in silver-halide photographic material. In this case, a photographic plate should be rotated in its plane by 90º between two exposures. It is shown that distribution of the total light energy near any minimum is a function with a rotational symmetry with respect to the coordinate point of this minimum.(1)In the limiting case, the 2-D holographic gratings for photographic material having the absolute contrast after development and fixing will represent repeated rows of circular transparent apertures over a dark background, whereas during the chemical development process the boundaries of circular transmitting apertures are practically smeared out (Fig. 1а).To the first approximation, the TDHG can be considered as a set of cameras obscura with apertures of the diameter d A capable of forming serially repeated images in a light-sensitive medium placed at a certain distance z from the TDHG. The required profile of the total energy distribution of light-sensitive medium exposure (depending on coordinates on the medium surface) can be obtained when illuminating it through the TDHG by a parallel beam at different angles to the grating surface normal. Here either continuous exposure or a set of discrete exposures can be used. For example, in order to form a microlens raster, a light-sensitive medium with a relief-phase response can be used. In this case, the distribution profile of the total energy exposure that is formed by the TDHG should be lens-like.Let us consider the TDHG formation for obtaining the raster of convergence microlenses. The most simple way is to * nina.

“…We assume that the ends of wave vectors k n of such waves are uniformly distributed over a ring the plane of which is parallel to the surface of the photosensitive medium. The complex ampli tude of each plane wave is written as (1) Then, the complex amplitude of the total wave in the plane of the photosensitive medium can be repre sented as (2) where and r τ are the tangential components of the wave vectors of plane waves and radius vector, respec tively. The intensity of the total wave in the hologram plane is given by Abstract-A method for formation of optical scatterers based on multiplex holograms is proposed.…”

“…As distinct from conventional diffusing glasses, holographic diffusers make it possible to con trol the width of the scattering indicatrix for more effi cient usage of the radiation energy of incandescent lamps, LEDs, diode lasers, etc. The results of [1,2] show that the phase relief structures on the silver halide photomaterials provide a transmittance of greater than 97% and a simultaneous decrease in the unscattered component to several fractions of percent. Holographic methods make it possible to control the characteristic size of the elements of spatial structure using the angle of convergence of the beams that inter fere upon hologram recording.…”

“…Holographic methods make it possible to control the characteristic size of the elements of spatial structure using the angle of convergence of the beams that inter fere upon hologram recording. An optical scatterer made of diffusing glass may serve as an object of the holographic procedure in the synthesis of a diffuser with the aid of the holographic method [1,2]. An alternative procedure involves the application of a dif fraction grating.…”
