摘要

介绍了一种减小聚焦光束尺寸的计算机生成全息图的设计方法。在迭代傅里叶变换算法中，重点是平行光束的排列及其相位和振幅的特定约束。聚焦光束减小到衍射极限的75%或更小。

Proximity amplitude and phase control for beam reduction using computer-generated hologram

Design method of a computer-generated hologram for reduction of the focused beam size is demonstrated. The key points are an arrangement of parallel beams and a specific constraint of their phases and amplitudes in the iterative Fourier transform algorithm. The focused beam was reduced to 75% or less of the diffraction limit.
