Paper Abstract

The implementation of paraxial diffractive elements with complex transfer functions is a difficult problem since current technologies impose restrictions to certain modulation domains. In optical information processing, addressable spatial light modulators are already used to implement diffractive elements. The spatial resolution of such modulators is strongly limited. Moreover, they are restricted to a certain modulation domain. In this paper, we examine how to make optimal use of the available space-bandwidth product of an SLM to realize optical functions on the basis of encoding methods in diffractive optics. Theoretical considerations are documented by an example, where a classical matched filter is encoded into a diffractive phase element.
