Improve the Light Beam Uniformity by Using a Serrated Circular Aperture and a Space Filter
摘要
详细研究了波纹光阑的菲涅耳衍射特性，提出并论证了利用波纹光阑和空间滤波器的结合使用能进一步有效地改善光束近场分布、抑制光束总体的衍射调制、提高光束填充因子。
Abstract
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.
