透镜列阵单元形状对光斑特性的影响

Influence of Element Shape of Lens Array on the Spot Characteristics

用标量衍射积分理论分析了透镜列阵的单元形状对准近场光斑特性的影响,并通过数值计算研究了不同单元形状(圆形、正方形、正六边形)透镜列阵的准近场光斑包络的结果,得到了与理论分析基本符合的结果。

Based on the scalar quantity diffraction integral theory,the influences of element shape of lens array on the quasi-near-field spot characteristics are analyzed.The intensity envelopes of different element shapes（circular or hexagon or square） on the quasi-near-field spots are calculated numerically by a computer.The simulated results of the envelopes of the spots agree qualitatively with the theoretical analysis results.
