    Abstract
    The purpose of this thesis is the empirical determination of the response of an optical spatial filter system to photographic detail edges. Spatial filtering in an optical system refers to a process in which the performance of the system is modified in terms of object size and shape. In its essentials the optical system tested is well known, with spatial filtering experiments having been performed as early as 1906. A renewed interest in recent years has been the result of the application of communication theory to optics. Reference is made to recent publications concerning the analytical treatment of coherent imagery in general and spatial filtering in particular as well as to more recent experimental studies. Theoretical considerations and analytical treatment are included in this thesis to an extent sufficient for the scope of the investigation. [TRUNCATED] The thesis is concluded with the recommendation that further work with the filter system be undertaken from the point of view of producing an optimum filter for a certain practical application. Also the recommendation is made that the system be used for harmonic analysis as a research tool or a classroom demonstration device.
