We report the realization of a new iterative Fourier-transform algorithm for creating holograms that can diffract light into an arbitrary two-dimensional intensity profile. We show that the predicted intensity distributions are smooth with a fractional error from the target distribution at the percent level. We demonstrate that this new algorithm outperforms the most frequently used alternatives typically by one and two orders of magnitude in accuracy and roughness, respectively. The techniques described in this paper outline a path to creating arbitrary holographic atom traps in which the only remaining hurdle is physical implementation.
我们报告了一种用于创建全息图的新迭代傅里叶变换算法的实现,该算法可将光衍射成任意二维强度分布。我们表明,预测的强度分布是平滑的,与目标分布的分数误差在百分之几的水平。我们证明,这种新算法在精度和粗糙度方面分别比最常用的替代算法通常高出一到两个数量级。本文所述技术勾勒出了创建任意全息原子阱的途径,其中唯一剩下的障碍是物理实现。
