Paper Abstract

The construction of digital holographic spatial filters using a high precision multiple gray-level plotting device is demonstrated. Examples of the use of such filters in a coherent optical system are presented, and analogous results obtained by computer processing are shown for comparison. The theory of sampled holograms and spatial filters is discussed in some detail.
