- W4384160227 abstract "基于几何稳相法求解调制相位，使用傅里叶透镜进行傅里叶变换，在后焦面处聚焦，得到对应的平顶光束，从而将圆形高斯光束整形为方形平顶光束，其中光路参数对整形质量将产生较大影响。实验中发现，方形平顶光束受零级光影响均匀性较差，因此详细分析了零级光产生的原因，提出了有效的解决方法，并对实验结果中出现的零级光通过叠加闪耀光栅直接移除。实验结果表明：移除零级光后方形平顶光束的能量利用率为72.3%，光束均匀性高达97.2%，优于传统整形方法。最后进一步分析了全息图与入射光束偏移量、离焦以及入射光束束腰半径对几何稳相法整形质量的影响，为几何法光束整形的应用提供了便利。" @default.
