Recently two optical interpretations of the fractional Fourier transform operator were introduced. We address implementation issues of the fractional-Fourier-transform operation. We show that the original bulk-optics configuration for performing the fractional-Fourier-transform operation [J. Opt. Soc. Am. A 10, 2181 (1993)] provides a scaled output using a fixed lens. For obtaining a non-scaled output, an asymmetrical setup is suggested and tested. For comparison, computer simulations were performed. A good agreement between computer simulations and experimental results was obtained.
最近，有人提出了分数阶傅里叶变换算子的两种光学解释。我们讨论了分数阶傅里叶变换操作的实现问题。我们表明，用于执行分数阶傅里叶变换操作的原始体光学配置[《美国光学学会杂志A》10, 2181 (1993)]使用固定透镜可提供缩放输出。为了获得非缩放输出，我们提出并测试了一种不对称设置。为了进行比较，我们进行了计算机模拟。计算机模拟与实验结果之间取得了良好的一致性。
