Image continuity at different levels of zoom for Moiré techniques
SPIE Proceedings, 2010Moire technique is a technique used for 2D and 3D imaging and surface characterization. Moire systems may have a range of zooms to image an object at different levels of details or Moire images may be combined (or compared) with images from other interferometers. So, it is needed to inter-relate images together in order to keep the continuity of the

Moiré pattern reduction by using special designed parallax barrier in an autostereoscopic display
SPIE Proceedings, 2010The moire pattern is caused by the spatial interference of two regular pattern structures. In the case of an autostereoscopic display, it's caused by the overlap of the parallax barrier and the black matrix among pixels of FPD. To minimize the moire effect, we simulate the relationship of brightness distribution and various design parameters of the ...

Moiréfree color halftoning using hexagonal geometry and spot functions
SPIE Proceedings, 2011A halftone configuration is presented that utilizes three or four rotated hexagonal screens, or more precisely, screens with hexagonally tiled clusters, for moire-free color printing. Halftone designers consider many options to deliver a screen with desirable characteristics, and often must settle for less than desirable results.

SPIE Proceedings, 2011
A complete set of ultra-long focal length measurement system based on the principle of Talbot effect and moire fringe technology has been developed. The numerical simulation is coded taking advantage of matlab. The errors deduced by errors of parameters of ultra-long focal length measurement is studied.

X-ray moiré patterns of silicon crystals with distortions caused by local concentrated forces
SPIE Proceedings, 2011We study the mechanisms of forming X-ray moire images arising under the action of one-dimensional rows of local concentrated forces at output surface of a surface of triple-crystalline-interferometer for the cases of orientation of them parallel and perpendicular to the vector of diffraction. Presence of constant phase shift of one of the interfering

Recording of periodic structures is employed, instead of printing techniques, for moire pattern to be generated. Diffraction gratings are utilized not only as substitutes of printing inks here but also to employ variation of visual appearance for revealing information encoded in a data-carrier structure. Two designs are analysed - one relying on very

MARCAS DO TRAUMA: SONHO E SOFRIMENTO PSICOLÓGICO EM “LÍBIA MOIRÔ, DE CONCEIÇÃO EVARISTO
Revista Ibero-Americana de Humanidades, Ciências e EducaçãoO universo da Literatura apresenta-se como um rico e dinâmico espaço não apenas de experiência estética e construção de sentidos, como também de diálogo com outras áreas do conhecimento. Assim, ao entrar em contato com narrativas, estreita-se, no processo de leitura, uma relação com as personagens, o que possibilita o ingresso na complexidade da ...

Composites Science and Technology, 2000
Abstract The deformation along cylindrical surfaces of holes in tensile-loaded laminated composite specimens was measured by means of new moire interferometry techniques. Two composite tensile specimens, fabricated from IM7/5250-4 pre-preg with ply lay-ups of [04/904]3s and [+302/−302/904]3s, were examined by newly developed moire interferometry ...
