白光放大全息图节约全息材料
Enlarging Holograms Under White Light, a Way to Save Holographic Material
摘要:
我们开发了在白光下使用全息屏幕的技术,于1989年首次向公众展示(3)(4),这表明了在1990年扩大全息图的可能性(5)。图1显示了我们如何在第一步中对视图进行编码。该图的平面是水平的,并且需要薄的垂直狭缝来以不同的顺序波长值投影场景的每个不同视图。解码的发生是因为投影的视图被全息屏幕(6)自然地角度重新分布。
英文摘要:
We developed techniques for employing holographic screens under white light, first exhibited to the public in 1989 (3) (4) which demonstrated the possibility of enlarging holograms already in 1990 (5). Fig. 1 shows how we encode views in a first step. The plane of the figure is horizontal, and a thin vertical slit is necessary to project each different view of the scene at a different sequential wavelength value. Decoding happens because the projected views are naturally angularly redistributed by the holographic screen (6).
