The effects of diffraction and interference on the images of sharp edges and slits viewed through amplitude diffraction gratings have been measured. The parameters investigated were grating line pitch, object-plane to grating-plane distance, and width of object slit. Microdensitometer tracings and isodensitograms of representative examples are included in the paper.
