Using a binary microlens of diameter 14 µm and focal length 532 nm (numerical aperture NA = 0.997), we focus a 633-nm laser beam composed of a mixture of radially and linearly polarized waves obtained by reflection of a linearly polarized Gaussian beam from a gold-coated subwavelength binary four-zone diffractive optical microelement (micropolarizer) of size 100×100 µm to a near-surface, near-circular focal spot of size (0.37±0.02)λ and (0.39±0.02)λ, where λ is wavelength. A linearly polarized light beam forms an elliptical focal spot with diameters (0.35±0.02)λ and (0.41±0.02)λ. Both focal spots have the area of 0.133λ². Subwavelength focusing using two microoptical components (a binary microlens and a micropolarizer) is suggested for the first time.

Nanofocusing by sharp edges

Published: September 2016

We show that the near-field nanofocusing of the electromagnetic field is possible to implement not only by means of metallic but also dielectric structures with sharp edges. The effect of the extraordinary enhancement of the longitudinal electric field component near the sharp edges of an optical element microrelief is shown using vector Rayleigh-Sommerfeld integrals. A finite element method is used for modeling the diffraction of the electromagnetic radiation by the edges of high-refractive-index metal and dielectric structures. It is shown that the focal spot size (full width at half-maximum) depends on the radius of curvature of the sharp tip. An optical scheme for sharp focusing, which consists of a concentrator collecting and directing the radiation onto a nano-focuser, is offered. A refractive axicon is suggested as the concentrator that directs the radiation on its vertex where an aluminium or silicon nanosphere is located (a nanofocuser). Illumination of this focuser by an optical vortex beam provides the nanofocusing with high diffraction efficiency. It is necessary to illuminate an axicon by a vortex beam of the first order or by a radially polarized beam. The scheme proposed is able to confine the radiation within a light spot of size l/400 at the half maximum of the intensity.

A theoretical and experimental study of a Hartmann sensor intended for measurements of light beam wavefronts and implemented on the basis of multielement amplitude masks with apodized apertures is presented. We perform a comparative analysis of the optical performance of the amplitude masks with hard-edge circular apertures and half-tone masks (HTMs) with apodized apertures forming smooth fast decaying optical responses on a photosensor. A technique for fabricating chromium HTMs is developed, which is based on laser thermochemical method of recording. This technique includes two main stages: first – the exposure of a chromium film by a focused laser beam, whose power is varied in a smooth and nonlinear manner versus the required density of HTM’s structure, and second – the developing of the film in a selective etcher. Specimens of HTMs consisting of 64×64 Gaussian apertures were fabricated and applied in a modified Hartmann sensor to measure the wavefront of powerful laser systems.

A method for calculating the difference between two arbitrary spatial phase distributions reconstructed from digital holograms is presented. The method is promising for application in double-exposure digital holographic interferometry, especially for the evaluation of phase variations in heavily noised or speckle-structure-modulated digital holograms, because it does not use the phase unwrapping procedure for each reconstructed spatial phase distribution. Instead, by analogy with classical double-exposure holographic interferometry, an interference pattern formed by two reconstructed object waves is calculated first. The interferogram thus obtained is then processed as a digital hologram by the same method that was used for reconstruction of physically recorded holograms. The advantages of the proposed method are demonstrated by both by the numerical computation of the difference of the phase distributions of speckle-structure-modulated wavefronts and the experimental observation of the laser-induced temperature gradients in an aqueous solution of a photosensitizer.

Published: September 2016

We studied a generalization of the family of Laguerre-Gaussian (LG) laser modes with asymmetrical intensity distribution. As the asymmetrical LG beam is propagating in a homogeneous medium, the asymmetry of its main (central) bright ring reduces, while the contrast of the rest rings increases. The number of bright rings coincides with that of a standard (symmetrical) LG mode. Using the expansion of the complex amplitude into the angular spectrum of plane waves, we calculated analytically the power of the asymmetrical LG beams and projection of their orbital angular momentum (OAM) on the optical axis. It is found that the normalized OAM (OAM per photon) is completely determined by the topological charge and the ratios between the shifts and the waist radius. We also found the conditions under which the normalized OAM coincides with the topological charge (as is the case for the optical vortices).

In this paper we substantiate and develop a new comparative diffusion morphology technique based on filters that allow geometrical changes in the images under comparison. Two alternative interpretations of the morphological projector using “absolute” and “relative” definitions of a morphological image shape are proposed. Diffusion morphology based on superposition of two Pytiev’s projectors on mosaic shapes is considered. Diffusion morphology based on 'reference' filters is proposed as a generalization of the approach. The advantage of using diffusion morphology compared to classical Pytiev’s projective morphology in change detection applications is demonstrated.
Optical trapping and moving of microparticles using asymmetrical Bessel-Gaussian beams

We study the optical trapping, rotating and moving of 5-mm polystyrene microspheres in asymmetrical crescent-shaped Bessel-Gaussian laser beams that carry the orbital angular momentum. The beams are generated by a liquid crystal microdisplay and focused by a microobjective with a numerical aperture of NA = 0.85. It is shown experimentally that while the topological charge of the beam remains unchanged, an increasing asymmetry of the beam causes a near-linear increase in the microparticles velocity. This serves to confirm that the orbital angular momentum (OAM) of the beam depends in a linear manner on the beam's asymmetry. The use of crescent-shaped beams can reduce the thermal exposure of biological objects during optical micromanipulation.

Ways and methods of modeling and calculating a holographic combiner for a virtual display are presented. On the one hand, they allow Denisyuk holograms with high diffraction efficiency independent of the field angle to be generated. On the other hand, they allow the advantages of the holographic combiner when compared with a multilayer dielectric mirror to be maximally realized. Optimization and search of the design parameters of elements of an optical setup for generating an aspherical wavefront for recording a Denisyuk hologram are based on ray tracing. These processes are greatly facilitated by the use of an intermediate model in the form of a thin transparency for phase delay. The phase delay of this transparency, the mirror geometry of the optical setup that forms the aspherical wavefront for recording the hologram, and the actual model of Denisyuk hologram in this article are described in the form adopted in the Zemax environment for surfaces such as Binary1, Extended polynomial and Optically Fabricated Hologram.
A copy-move detection algorithm based on binary gradient contours
Authors:   Samara State Aerospace University, Kuznetsov A. ,   Image Processing Systems Institute, Russian Academy of Sciences, Myasnikov V. ,   Samara State Aerospace University,   Image Processing Systems Institute, Russian Academy of Sciences
Published: September 2016

Copy-move is one of the most obvious ways of deliberate distortion of digital images in order to conceal the information contained in them. The process of duplicate embedding consists in copying an image fragment and pasting it within the same image. Prior to pasting, the fragment can be distorted using transformations such as contrast enhancement, noise adding, scaling, rotation, and combinations thereof. Existing approaches to copy-move forgery detection are based on calculating feature vectors for overlapping blocks of an image and then using these vectors to find the closest regions in Euclidean space. In this paper, we propose features based on binary gradient contours, which are resistant to contrast enhancement, additive noise and JPEG compression. We also present results of conducted experiments for demonstrating the proposed algorithm effectiveness for a range of distortion parameters. The research also involves comparing features based on binary gradient contours with features based on various forms of local binary patterns.

We discuss a problem of reducing the thickness of lines of the contact pattern masks produced by laser ablation of thin films of refractory metals and used when synthesizing the micro-relief of diffractive optical elements (DOEs). For a contact mask for a DOE on molybdenum, patterns with features in the range 0.25-0.3 µm were recorder by laser ablation on 40-nm thick films. This is approximately 3 times smaller than the characteristic dimensions obtained by thermochemical recording chromium films of the same thickness in the standard process. A microrelief of height of up to 300 nm was formed in a quartz substrate by reactive ion etching in an inductively coupled plasma through the mask. We show that thin molybdenum films can have promising applications as metallic masks when synthesizing a DOE microrelief.

A partir da publicação das Diretrizes Curriculares Nacionais para os cursos da área da saúde, impulsionadas pelas transformações do Sistema Único de Saúde, a Atenção Básica passa o ponto de convergência das políticas de educação e saúde. Apesar de haver muito debate e um grau significativo de mobilização, aparentemente faltam elementos que desencadeiem nas escolas, processos efetivos de mudança. A condução das mudanças deve ser realizada por meio de ações e processo avaliativo condizente com os resultados esperados. Neste sentido, o objetivo do trabalho foi desenvolver um instrumento de autovaliação da integração ensino-serviço no âmbito da Atenção Básica, a partir da leitura e análise de documentos oficiais das políticas de educação e saúde. O instrumento foi desenvolvido a partir do referencial teórico de Donabedian, com dimensões que consideram tanto estrutura que favoreça o desenvolvimento das atividades, assim como o próprio processo de desenvolvimento das atividades, especialmente o processo de trabalho e atenção integral na Atenção Básica, com definição de padrão de qualidade para o desenvolvimento das competências requeridas. Espera-se que o instrumento possa nortear o processo de mudança da formação mais ajustadas a realidade dos serviços e as necessidades de saúde da população.

GASTOS PÚBLICOS E CRESCIMENTO ECONÔMICO NO BRASIL DA SEGUNDA METADE DO SÉCULO XX: uma abordagem do Teste de Causalidade de Granger
Authors: Rodrigues Rodrigo Vilela , Teixeira Erly Cardoso
Published: September 2016

A relação entre gasto público e PIB é tema recorrente de debate na literatura econômica nacional e internacional, com a relevância do setor público no crescimento econômico avaliada em termos de elasticidade do produto com relação a esses gastos. No entanto, menos se fez no sentido de verificar se crescimento econômico é causa ou consequência do crescimento dos gastos públicos, objetivo básico do presente trabalho. Para tal, foi utilizado o teste de causalidade de Granger entre variáveis que representassem o PIB e os gastos governamentais em distintas especificações, para as três esferas de governo. De acordo com os resultados auferidos, conclui que os gastos públicos são, em sua maioria, consequência e não causa de crescimento do PIB, o que corrobora a Lei de Wagner e possibilita importantes conclusões acerca dessa complexa relação na economia brasileira, durante a segunda metade do século passado.

Authors: Melo Licemar Vieira , Paese Cláudia Regina
Published: September 2016

O objetivo deste artigo é analisar as diretrizes, as prioridades e a estrutura operacional do Programa Fome Zero, bem como identificar como nele ocorreu a articulação do Estado e da Sociedade Civil. O referido programa governamental, implementado no Brasil em janeiro de 2003, tinha como propósito combater a fome no país – garantindo o acesso à alimentação, direito humano reconhecido internacionalmente. Este artigo, além de fontes documentais e pesquisa bibliográfica, utiliza dados coletados no período compreendido entre 2003 e 2004.   Conclui que o programa garantiu espaços de interlocução entre diversos atores sociais, que não mais atuam de maneira distinta e dissociada. Verifica, ainda, que foi assumido o discurso de cogestão das políticas sociais para o enfrentamento de questões como a fome no Brasil.
POLÍTICA HABITACIONAL E (IM)PERMANÊNCIA DE FAMÍLIAS REMANEJADAS: estudo sobre o projeto de urbanização Vila da Barca em Belém, Pará
Authors: Souza Alessandra Kelma de , Santana Joana Valente
Published: September 2016

O artigo apresenta uma reflexão sobre a atual orientação da política habitacional brasileira de intervir em áreas de assentamentos precários, sem a remoção dos moradores, de modo a garantir sua permanência nos locais infraestruturados. Ressalta que a partir da execução do Projeto de Urbanização e Habitação da Vila da Barca, na cidade de Belém, a investigação procurou verificar em que medida essa orientação garante efetivamente a permanência dos moradores removidos para um conjunto habitacional. Com base no referencial da teoria social marxiana,a pesquisa de campo revela que, ao contrário do que é propagado pelo discurso governamental, a remoção de famílias oriundas de assentamentos precários para o conjunto habitacional desarticulou as estratégias de sobrevivência das famílias, criando obstáculos ao pagamento das taxas de serviços urbanos na nova moradia. Conclui que após o processo de remanejamento, há uma tendência de venda de imóveis, o que revela a questão da impermanência das famílias no pós-remanejamento.
SOBRE OS BASTIDORES DO PROCESSO DE FORMULAÇÃO DE POLÍTICAS PÚBLICAS: considerações acerca da saúde bucal no Brasil
Authors: Garcia Danielle do Valle
Published: September 2016

Este trabalho trata do processo de formulação de políticas específicas, no contexto da política de saúde. Busca compreender o processo de construção da Política Nacional de Saúde Bucal no período de 2000 a 2004, visando identificar os elementos que possam ter contribuído no processo. O estudo possibilitou comparar dois processos de formulação de políticas distintos, a saber: a entrada da saúde bucal no PSF e a Política Nacional de Saúde Bucal Brasil Sorridente. No primeiro momento, a política foi forjada aproveitando as janelas de oportunidades abertas pela ênfase na atenção básica e na adoção do PSF nas instâncias superiores. No segundo momento, ao contrário, um grupo com forte matiz político-partidário formulou um projeto político para a saúde bucal, ainda fora do espaço institucional do governo. Uma vez ocupado esse espaço, o que envolveu uma articulação direta com a Presidência da República, deu-se a forma da Política nacional de Saúde Bucal.
