Abstract
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.
