Show Abstract
The use of highly viscous formulations based on multifunctional acrylates and on various sensitizers allows holograms to be recorded through a photochemically induced polymerization. After a preillumination under homogeneous deep UV exposure, these materials are able to generate a tridimensional network in the cavity of which residual monomers can diffuse easily. When irradiated holographically, these systems become more and more rigid and reach, ultimately, a stage of complete photochemical inertness so that they do not require any chemical or physical post-treatment. Depending on the structure of the sensitizer, the range of sensitivity extends over the visible and near infrared up to 850 nm. At best, no more than 30 mJ/cm-2 are required to record a permanent hologram at 514 nm.

Show Abstract
The laws of the change in the spectral power density of optical noise (Wiener spectrum) of a monolayer of particles depending on their optical properties and concentration have been studied from the view point of the model amplitude-phase screen. It is shown that the account of the spatial correlation in the positioning of inhomogeneities and of the interference between scattered waves leads to qualitatively different laws of optical noise behavior in comparison with rarefied optical image recording systems.

Show Abstract
We present new, easy to use methods of measuring the fidelity of phase conjugated beams employing a classical system for image acquisition and processing, coupled to a personal computer. Two methods are based on intensity distribution changes measurements and the third is an interferometric evaluation of the wavefront reconstruction. These methods are applied in phase conjugation fidelity studies in a degenerate four wave mixing experiment using a He-Ne laser and a Bi12TiO20 (BTO) photorefractive crystal. A comparison between the proposed methods, and also with other techniques currently used for phase conjugation fidelity studies, is made.

Show Abstract
Among the wide range of photoinduced phenomena exhibited by the chalcogenide vitreous semiconductors (ChVS) the most frequently used in a variety of optical imaging applications are the photodoping effect (or the effect of photostimulated diffusion of metal into ChVS, one of the most widely studied) and the effect of photoinduced solubility change of ChVS layers. Both effects lead to substantial changes in the solubility rate of chalcogenides and this enables us, with the help of selective etching, to produce various relief images. In this paper the peculiarities of holographic optical elements, including holographic diffraction gratings, focusing elements (Fresnel lenses, etc.), phase-relief holograms production on the base of ChVS layers (As-S-Se-composition), are considered.

From this an effective transfer function for imaging of rough surfaces is developed, based on the Kirchhoff approximation. It is described how confocal imaging can be used to investigate various scattering mechanisms, and can be used for reconstruction of surface profiles in the Kirchhoff approximation.

Show Abstract
The field in the correlation plane of a referenceless hologram used as a matched filter is shown to be the result of interference between different components of the reconstructed and the reconstructing fields. The intensity of the unchanged parts of the field is shown to depend on the correlation between the original field, and to be described by a mutual correlation function c(x,y). Limiting cases, c(x,y) yields 0 and c(x,y) equals 1 are considered. Also considered is the case when changes in the readout fields are limited to small changes in the secondary source phases.

Show Abstract
There are more than a dozen different methods of diagnostic and control of the structural purity of materials which are used in modern micro- and optoelectronics. Each of them has their own strong and weak points, range and fields of use. Usually a couple of different methods are used in research together. The advantage of using x-ray methods against optical (in solving the problem of distorted crystal) is that interferention of coherent beams is not on artificial diffraction lattice but on crystal lattice of the researching object. It permits us to expand researching ranges of crystal structures distortions. The privilege of x-ray methods (like x-ray interferometry and diffractometry) is that they are nondestructive, noncontact, fast, do not require expensive equipment, and are highly sensitive. Unique information about deformation locations and electronic density as a function of width (from a few monolayers) can be determined from their use.

Show Abstract
Harnessing phased acoustic arrays for extending the operating range of optical deflectors is well known and investigated by a number of researchers. Usually, it was supposed, that acoustic waves are excited in contra-phase, or with phase difference linear dependent on wave frequency. These modes of excitation are easily achieved in deflectors of simple design, but they do not provide strict consistency between acoustic wave front and Bragg angle when scanning the optical beam. To investigate possibilities of multielement deflector with individual control of channels in phased acoustic array we examined light diffraction on a sequence of ultrasonic waves in isotropic medium.

This paper describes in detail the effective procedure for Karhunen-Loeve basis synthesis, offered by the authors for statistical ensembles, permitting a limited size teaching set. Unlike the classical Karhunen-Loeve procedure, the main factor, restricting its application and determining the number of required calculations for basis formation, is not the dimension of the encoding signal itself but the number of elements in the input basic set. This allows us to apply this procedure to the objects of grate capacity (up to 106 - 108 counts), that is usual for optical processed signals. Examples of effective real signal coding are given.

We illustrate a technique of constructing a single crystal photorefractive (PR) fiber hologram. Because of its physical length (a few centimeters), high angular and wavelength selectivities can be achieved, in which massive holographic data storage can be performed.

Show Abstract
Introducing either a uniform square shaped or chirped sinusoidal corrugation onto the gain and/or the refractive index of an optical fiber, it is theoretically investigated that extremely high-gain optical fiber amplifier is feasible for optical communication, signal processing, and measurement fields. A gain of more than 15 dB is obtainable with the gain corrugation (Delta) (gamma) equals 0.05/m around a specific corrugation period (xi) equals 0.333 in comparison with a uniform gain fiber. Inducing the index corrugation (Delta) n in addition to (Delta) (gamma) tends to shorten the effective fiber length for yielding the same gain. Furthermore, introducing the chirping into the gain corrugation, its transmission gain is more enhanced by about 5 dB and tolerance of the setting of the corrugation period (xi) is rather relaxed with wider spectrum bandwidth.

Show Abstract
The guided-mode resonance characteristics of planar dielectric waveguide gratings with arbitrary grating slant are discussed. These all-dielectric structures can operate as high- efficiency, narrow-line reflective filters. Expressions and graphs defining the resonance regimes and the resonance locations and their separations for TE and TM modes are given. It is shown that the typically asymmetric filter response found when the filter is in asymmetric waveguide-grating geometry can be made nearly symmetric by proper choice of the thickness. A three-wave analytical solution for the case of normal incidence on an unslanted waveguide grating is derived and verified by comparison with rigorously calculated results. Example results describing the resonance behavior under Gaussian beam illumination show that if the angular spectrum of the Gaussian beam can be accommodated within the angular corridor of the waveguide-grating filter, a high-efficiency resonance can occur. There are numerous potential applications of the guided-mode resonance effects described in this paper such as laser resonator mirrors and narrow-line reflection filters as well as new thin-film antireflection resonant structures, polarizers, and electro-optical switches.

Show Abstract
Recent attempts aimed at developing holographic neural networks and associative memories have stimulated interest to the problems of coherent correlation processing of optical data. Finding new approaches to the reconstruction of the optical field amplitude and phase from its intensity distribution is also a topical problem. In the present work, correlation filters, based on referenceless holograms (RH), are proposed which are the necessary components of neural networks and associative memories. The RH was first introduced as a generalized correlation filter by Van Heerden. A RH is the scattered field intensity recorded on a recording medium. Image reconstruction from such a hologram is based on its associative properties, which take effect when a field (or its part) which is the same as (or similar to) the original object field, is used as the reconstructing field.

Show Abstract
Imaging properties of a second-order hologram (SOH), i.e., a thin off-axis hologram with the amplitude transmittance involving expansion terms up to quadratic in exposure, are investigated. It is shown that by reading such a hologram by a partial or distorted object image it is possible to obtain a complex conjugate associative response, i.e., reconstruct a conjugate object image. The advantages of a SOH over the linearly recorded 2-D and even 3-D ghost- image holograms are in that it is capable of reproducing the original intensity distribution in the conjugate image and permits a reciprocal associative reconstruction of noninterfering complicated wave fronts. Also discussed are the associative properties of volume SOH.

Show Abstract
One of the fundamental applications of integrated optics is the development of miniature optical gyros for navigation and airborne vehicle control systems. The integrated optical ring passive resonator (RPR) was proposed as one of the possible realizations of a sensitive element for such gyros. It presents a closed-loop channel waveguide made on a substrate of optical quality with which two Y-splitters are optically and symmetrically connected. The first splitter is connected in a homogeneous section with the external radiation source and serves for excitation in the closed-loop wave-guide for the two light waves, one of which propagates in clockwise direction and the other in counterclockwise direction. The second Y-splitter extracts some part of circulating radiations out of the closed-loop waveguide circuit and directs it to the photodetector, detecting the intensity of a superpositioned field.

Show Abstract
The dynamics of lasing of the CdS-microlaser have been studied experimentally under the conditions of 10 ns pumping pulses of N2-laser with (lambda) equals 0.3371 micrometers . It was found that the microlaser oscillates in pulse operation during single pulse pumping. The number of pulses and their durations depend on the efficiency of pumping. Depending on laser threshold overrun we observed from 1 to 6 pulses with durations (FWHM) 0.172 to 0.735 ns. We assume that the CdS-microlaser oscillation's peculiarities are similar to passively Q- switched lasers with a nonlinear saturated absorber. This platelet microlaser may be used in monolith integrated opticalics for optical computers and nonlinear optical devices and systems.

In the past few years advances in the fabrication technology of diffraction optical elements have given rise to the development of a variety of interferometric devices for various applications. At present obtaining high-quality highly efficient hologram and ruled diffraction gratings as large as several hundred millimeters in size is no longer a problem. This enables us to design a twin-wave interferometer which is equivalent to the conventional four-mirror Mach-Zehnder interferometer with a working field of 300 - 400 mm, but our device is characterized by a significantly higher vibration-resistance capability and easy to adjust.

Show Abstract
Presently the creation of advanced computational means is closely connected with the development of neuron-like structures with the computation principle based on the dynamic evolution process of these structures under the input signal effect. There are numerous physical principles of implementation of neuron-like computational structures. However, the most promising is the creation of such structures on the optical principles basis. Such prospects are first of all related to the spatial character of the information transmitted by the optical radiation.

Show Abstract
The new method of non invasive determination of blood components concentration -- bilirubin and hemoglobin -- was analyzed with the help of optic spectra of reflection from the skin surface and subcutaneous tissues. It is based on the registration of non-linear relation between optoelectronic characteristics of spectra of reflection, received and worked up for some wavelengths and concentration of studying components. This correlation is manifested most brightly and differs radically from a linear one in its sphere of relatively high concentrations with regard to patients.
