For many applications you want to limit or remove the *diffracted*
light though an aperture, so that the light arriving at the imaging
plane is more closely described by the geometrical optics
approximation.
Intuitively, it would seem if the edge of the opening were rounded
rather than sharp, less diffracted light would be able to bend around
to enter the aperture. This would be particularly true if the radius of
curvature of the edge was large with respect to the wavelength.
Anyone know of references that address diffraction through apertures
with a rounded edge?
