Abstract EN
The images of a straight edge in coherent illumination produced by an optical system with circular aperture and apodized with multiple filters have been studied.
The most common problem encountered in the coherent-imaging techniques is the edge-ringing.
To minimize the edge-ringing, multishaded aperture method has been proposed.
Image intensity distribution curves are drawn and edge-ringing values are evaluated.
The results are compared to that of the airy case with the use of single, double and triple filtering.
