In ordinary holography reconstructing a virtual image, the hologram must be wider than either the visual field or the viewing zone. In this paper, an economical method of recording a wide-viewing-zone wide-visual-field 3-D holographic image is proposed. In this method, many mirrors are used to collect object waves onto a small hologram. In the reconstruction, a real image from the hologram is projected onto a horizontally direction-selective stereoscreen through the same mirrors. In the experiment, satisfactory 3-D images have been observed from a wide viewing zone. The optimum design and information reduction techniques are also discussed.
在普通全息术中重建虚像时，全息图必须比视场或观察区更宽。本文提出了一种记录宽观察区宽视场三维全息图像的经济方法。在该方法中，使用多个镜子将物波收集到一个小全息图上。在重建过程中，全息图的实像通过相同的镜子投射到水平方向选择性立体屏幕上。在实验中，从宽观察区观察到了令人满意的三维图像。还讨论了优化设计和信息缩减技术。
