我们目前的实验结果分数傅里叶变换（FRFT）系统实现可编程透镜写到液晶空间光调制器（LCSLM）。因为焦距可以改变，所以可以在不改变光学设置的情况下获得不同阶的FRFT。LCSLM可以非常容易地实现更复杂的操作，包括实现FRFT和变形变换的同时阶。
We present experimental results for a fractional Fourier transform (FRFT) system implemented with programmable lenses written onto a liquid-crystal spatial light modulator (LCSLM). Because the focal length can be changed, different orders of the FRFT can be obtained without changing the optical setup. The LCSLM can very easily implement more complicated operations, including the realization of simultaneous orders of the FRFT and anamorphic transforms.
