    • The present invention concerns methods and devices for creating and printing variable size and variable resolution holographic stereograms and holographic optical elements using computer rendered images of three-dimensional computer models or using computer processed images. The present invention is an apparatus and method for printing one-step, full-color, full-parallax holographic stereograms utilizing a reference beam-steering system that allows a reference beam to expose a holographic recording material from different angles. More particularly, a coherent beam is split into object and reference beams. The object beam passes through an object beam unit in which a rendered image is displayed, while the reference beam passes through the reference beam-steering system. The object and reference beams interfere with each other at an elemental hologram on a holographic recording material. A computer controls the exposure time and the movement of the recording material and may also render the images displayed in the object beam unit. In addition, the computer may also store the images before they are displayed in the object beam unit. Also, the present invention may also utilize a voxel-control lens placed in the path of the object beam and in close proximity to the holographic recording material to control the resolution of a holographic stereogram. In addition, the present invention may also utilize interchangable band-limited diffusers and reference-beam masking plates. Furthermore, the present invention incorporates viewing zone techniques to the rendering process for one-step, holographic stereograms to produce animated, one-step, holographic stereograms.
    • 本发明涉及使用三维计算机模型的计算机渲染图像或使用计算机处理的图像来创建和打印可变尺寸和可变分辨率全息立体图和全息光学元件的方法和装置。 本发明是一种用于使用参考光束转向系统来打印一步全色全视差全息立体图的装置和方法,该参考光束转向系统允许参考光束从不同角度曝光全息记录材料。 更具体地,相干光束被分成对象和参考光束。 物体光束通过其中显示渲染图像的物体光束单元,而参考光束通过参考光束转向系统。 物体和参考光束在全息记录材料上的元素全息图彼此干涉。 计算机控制曝光时间和记录材料的移动,还可以使图像显示在物体光束单元中。 此外,计算机还可以在将图像显示在对象光束单元之前存储图像。 此外,本发明还可以利用放置在物体光束的路径中并且靠近全息记录材料的体素控制透镜来控制全息立体图的分辨率。 此外,本发明还可以利用可互换带限扩散器和参考光束掩模板。 此外,本发明将观察区技术结合到一步全息立体图的渲染过程中以产生动画的一步全息立体图。
