Abstract

A partially coherent Koehler-illumination imaging system equipped with complementary masks in source and pupil planes can be used to perform image enhancement operations such as directional or non-directional edge enhancement and emphasis of spatial bandpass features. With many objects the use of complementary masks results in high-contrast images. Underlying principles are explained and preliminary experimental results presented.
