On the Image of the Phase Microscope with Cross-shaped Phase Plate

Abstract

The improved phase microscope with cross-shaped phase plate was constructed and we studied into the image of this microscope. The amplitude grating was used for the test-piece. There is a strong tendency for boundaries between areas of transparent and opaque parts to be delineated by an abrupt change of intensity. In this paper, this abrupt change (edge effect) and the contrast of image were studied.
