| 摘 要： | 利用一发散点光源和一束倾斜平行光制作出在两个垂直方向上具有不同焦距的变形全息透镜,且用此全息元件实现了变形分数傅里叶变换。变形全息透镜两个方向上的焦距随全息记录条件和再现条件而变化,分析了用这种全息透镜实现变形分数傅里叶变换的条件。实验表明,用该元件能够方便地实现任意级次的变形分数傅里叶变换。

| Abstract: | The anamorphic fractional Fourier transform is a new concept which has much important application in optical information processing field.The anamorphic fraction Fourier transform is realized using anamorphic hololens,which is made using a dot light source and an inclined parallel light with different focus length in the x and y directions.The focus length of anamorphic hololens is related to the condition of record and reconstruction.The condition to realize anamorphic Fourier transform using this kind of hololens is given.The experimental result shows this transform method is convenient and feasible. |
