Improve the Light Beam Uniformity by Using a Serrated Circular Aperture and a Space Filter
The features of Fresnel diffraction are studied of the serrated aperture in this paper. We have proposed and demonstrated that using a serrated circular aperture and a spatial filter could effectively improve the light beam uniformity and suppress the intensity ripples for a large Fresnel numbers.
