ESTADO DA TÉCNICA. TECHNICAL STATE.
Técnicas e equipamentos para veiculação de imagens holográficas, com suas diversas peculiaridades, já são bastante conhecidos no estado da técnica. No que se refere ao estudo desta matéria, quando uma imagem é criada, apresentada ou registrada em duas dimensões elaboradas de tal forma a proporcionarem a ilusão de terem três dimensões são denominadas "holografias", porém, não é apenas mais uma simples forma de visualização em três dimensões, mas sim um processo de se codificar uma informação e se recriar integralmente esta mesma informação. Techniques and equipment for the transmission of holographic images, with their various peculiarities, are already well known in the state of the art. As for the study of this subject, when an image is created, presented, or recorded in two dimensions designed to give the illusion of having three dimensions, it is called "holographs," but it is not just another form of visualization. in three dimensions, but rather a process of coding information and recreating that information in its entirety.
Na área da comunicação, a holografia é utilizada como um "display" de alto impacto visual o que resultou no seu uso comercial como elemento promocional. Já nas artes visuais diversos artistas a usam como uma forma de expressão. Existe no mercado alguns instrumentos desenvolvidos para este tipo de atividade, no que se refere à sua reprodução. In the area of communication, holography is used as a display with a high visual impact which has resulted in its commercial use as a promotional element. Already in the visual arts several artists use it as a form of expression. There are some instruments developed in the market for this type of activity as regards its reproduction.
Ainda sobre a técnica utilizada na área da comunicação, esta foi denominada "Pepper's Ghost", popularizada por John Henry Pepper no século XVI, consistindo em uma técnica de ilusionismo utilizada em teatro e em alguns truques de mágica. Usando placas de vidro e técnicas de iluminação especiais, fazem objetos aparecerem e desaparecerem, tornar-se transparente ou, fazer um objeto se transformar em outro. Hoje, esta técnica está popularizada pelo uso de televisores e projetores em combinação com lâminas de diversos materiais como vidro, acrílico, etc. Still on the technique used in the area of communication, this was called "Pepper's Ghost", popularized by John Henry Pepper in the 16th century, consisting of a technique of illusionism used in theater and some magic tricks. Using glass plates and special lighting techniques make objects appear and disappear, become transparent, or make one object transform into another. Today, this technique is popularized by the use of televisions and projectors in combination with blades of various materials such as glass, acrylic, etc.

Em hologramas normais gerados em computador, alguém determina as frentes de ondas necessárias para a reconstrução de um objeto; isto não é feito diretamente na presente invenção; ao invés disso, alguém determina as frentes de ondas em uma janela de observação que seriam geradas por um objeto real localizado na mesma posição do objeto reconstruído. Alguém pode então retro- transformar estas frentes de ondas no holograma para determinar como o holograma necessita ser codificado para gerar estas frentes de ondas. Um holograma apropriadamente codificado pode então gerar uma reconstrução de uma cena tridimensional que pode ser observada colocando os olhos no plano da janela de observação e olhando através da janela de observação. On December 22, 2005, patent application PI0517159-8 was filed, the present invention consisting of a method of computing a hologram by determining the wavefronts at the approximate position of the observer's eyes that would be generated by a real version of an object. to be rebuilt. In normal computer-generated holograms, one determines the wavefronts needed to reconstruct an object; This is not done directly in the present invention; instead, one determines the wavefronts in an observation window that would be generated by an actual object located at the same position as the reconstructed object. One can then backtrack these wavefronts into the hologram to determine how the hologram needs to be encoded to generate these wavefronts. A properly coded hologram can then generate a reconstruction of a three-dimensional scene that can be observed by placing the eyes in the window plane. observation and looking through the observation window.
Em 15.10.1998, requereu-se a patente PI 9812925-2, referindo-se a um sistema para a produção de uma imagem dinâmica para uso em holografia, que inclui uma fonte de luz que se propaga através de um modulador de cristal líquido disposto no caminho da fonte de luz. A saída do modulador LC passa luz modulada através de um conjunto de lentes que em si próprio guia a luz para um modulador de luz espacial opticamente endereçado. A imagem real resultante do modulador de luz espacial opticamente endereçado pode ser usada em holografia. A taxa de quadros de endereçamento do modulador a cristal líquido é substancialmente maior que a taxa de quadros do modulador de luz espacial opticamente endereçado. Patent Application PI 9812925-2 was applied on 15.10.1998 for a system for producing a dynamic image for use in holography which includes a light source propagating through a liquid crystal modulator arranged in the path of the light source. The output of the LC modulator passes modulated light through a lens assembly which in itself guides the light to an optically addressed space light modulator. The resulting real image of the optically addressed space light modulator can be used in holography. The addressing frame rate of the liquid crystal modulator is substantially higher than the frame rate of the optically addressed space light modulator.

On October 15, 1997, MU 7702757-4 was filed as a system capable of measuring residual stresses on workpiece surfaces using the combination of blind hole method and electronic holography as a measuring principle.

Em uma concretização o filme de controle de luz compreende uma camada dianteira, uma camada de núcleo, e uma camada traseira, sendo que esta pode ser considerada como um plano de referência, por intermédio dp qual um deslocamento lateral no filme dianteiro resulta em comprimento de onda seletivamente, e um correspondente deslocamento na camada de núcleo resulta em satisfatório bloqueio de luz de ordem zero. A luz resultante é uma fonte pseudo-monocromática tendo coerência suficiente para aplicação como um feixe de reconstrução de holograma. On 28.1 1.1994, PI 9408175-1 was applied, which consists of a process of producing a master hologram of a physical system and light control film assembly for use in a hologram display apparatus. a holographic image reconstruction apparatus includes a white light source, diffraction grating (1112) for generating zero-order diffracted light and at least first-order diffracted light, and light control film that is configured to block order-diffracted light zero facilitates the passage of a desired bandwidth of first-order diffracted light therethrough. In one embodiment the light control film comprises a front layer, a core layer, and a back layer, which can be considered as a reference plane, whereby a lateral shift in the front film results in a length of wave selectively, and a corresponding shift in the core layer results in satisfactory zero-order light blockage. The resulting light is a pseudo-monochromatic source having sufficient coherence for application as a hologram reconstruction beam.
