当全息图只记录在照相底片上的一系列小区域上时，全息图上的信息减少了。当观察这样的全息图时，观察者有一种通过屏幕观察物体的恼人感觉。本文提出了一种消除这种“屏幕效应”的方法。给出了信息减少与分辨率损失之间的关系。还计算了重建给定分辨率的全息图所需的可分辨点的数量。除了一个数值因子外，该公式与积分摄影公式相同。
The information on a hologram is reduced when the hologram is recorded on only an array of small areas on the photographic plate. When looking at such a hologram the observer has the annoying sensation of observing the object through a screen. A method is shown for eliminating this “screen-effect”. The relation between the information reduction and loss of resolution is given. The number of resolvable points on the hologram needed for a reconstruction of given resolution is also computed. Apart from a numerical factor, the formula is identical to one derived for integral photography.
