    Abstract: Изобретение относится к области информационных технологий и предназначено для визуализации трехмерных изображений. Техническим результатом является создание электрически управляемых фазовых объемных дифракционных решеток и, на их основе, экранов для отображения объемных цветных изображений. Способ заключается в том, что осуществляют освещение пучком оптического излучения одновременно блока матриц пикселей, в котором матрицы установлены параллельно друг другу, причем освещают матрицы с той же стороны, с какой наблюдают изображение, при этом в качестве изменяемой оптической характеристики пикселей во всех этих матрицах используют показатель преломления. Устройство включает экран, предоставляющий собой многослойную структуру, которая содержит чередующиеся слои материала, обладающего электрооптическим эффектом, и слои прозрачного материала, не обладающего этим эффектом. Все слои материала, обладающего электрооптическим эффектом, электрически изолированы друг от друга и каждый из них выполнен в виде матрицы электрически управляемых элементов-пикселей.

    Abstract: A method for producing a 3D image includes providing a pixel-by-pixel map over a preselected aperture of relative phases for coherent light scattered by or transmitted through a desired scene. The method includes positioning micro-mirrors of a reconfigurable mirror array to produce reflected light whose wave front has the pixel-by- pixel map over the- preselected aperture in response to the array being illuminated with a coherent light beam. The method includes illuminating the reconfigurable mirror array with the coherent light beam to enable producing a 3D image of the desired scene.

    Abstract: Fast processing, at video rates, of information represented in digital holograms is provided to facilitate generating and displaying 3-D holographic images representative of a 3-D object scene on lower-resolution display devices. A holographic generator component (HGC) can receive or generate a hologram representing a 3-D object scene. The HGC can downsample the hologram based on a fix, jitter downsampling lattice, and can interpolate, through pixel duplication, the downsampled hologram to generate a low-resolution hologram that can be displayed with a low-resolution display device. A grating can be overlaid on the display device, wherein the grating can be generated based on the same jitter downsampling lattice used to downsample the hologram. The integration of the grating and low-resolution hologram can facilitate displaying, on lower-resolution display devices, holographic images that can have the resolution, to a desirably good approximation, of the original hologram.
