摘要： A single method and apparatus for producing many of the most common types of hologram from digital data is disclosed. The data are generated entirely by a computer as a 3-D (animated) model or from multiple 2-D camera images taken of a real 3-D(moving) object or scene from a plurality of different camera positions. The data are digitally processed and displayed on a small high resolution spatial light modulator (SLM). A compact low energy pulsed laser is used to record composite holograms. The present invention permits the creation of restricted or full parallax master transmission or reflection type composite holograms, known as H1 holograms, that can be copied using traditional methods. Alternatively the same invention and apparatus permits the direct writing of holograms without the need to pass through the intermediate stage of the H1 transmission hologram.
摘要翻译：公开了用于从数字数据产生许多最常见类型的全息图的单一方法和装置。数据由计算机完全由3D（动画）模型产生，或者由多个不同摄像机位置的真实3-D（移动）对象或场景拍摄的多个2-D摄像机图像生成。数据被数字处理并显示在小型高分辨率空间光调制器（SLM）上。使用紧凑型低能量脉冲激光来记录复合全息图。本发明允许创建可以使用传统方法复制的被称为H1全息图的限制或全视差主传输或反射型复合全息图。或者，相同的发明和装置允许全息图的直接写入，而不需要通过H1传输全息图的中间阶段。

摘要： A single method and apparatus for producing many of the most common types of hologram from digital data is disclosed. In one embodiment the data are generated entirely by a computer as a 3-D (animated) model. In another embodiment the data are generated from multiple 2-D camera images taken of a real 3-D (moving) object or scene from a plurality of different camera positions. The data are digitally processed and displayed on a small high resolution spatial light modulator (SLM). A compact low energy pulsed laser, which avoids the usual vibration problems encountered at high rates of production and the installation in normal working environments, is used to record composite holograms on an holographic emulsion using a special optical design. The present invention permits the creation of restricted or full parallax master transmission or reflection type composite holograms, known as H1 holograms, that can be copied using traditional methods to produce full or single colour rainbow white-light transmission holograms, achromatic white-light transmission holograms or single or full-colour white-light reflection holograms. Alternatively the same invention and apparatus permits the direct writing of full or single colour rainbow white-light transmission composite holograms, achromatic white-light transmission composite holograms or single or full-colour white-light reflection composite holograms without the need to pass through the intermediate stage of the H1 transmission hologram. The present invention allows the creation of a compact rugged machine that is capable of producing holograms covering a large size range. In addition the invention produces holograms that can be tiled together to form composite holograms much larger than the component panels.
