摘要
利用失调光学系统的衍射积分公式 ,分析了失调的Lohmann分数傅里叶变换光学系统和准非对称非均匀介质的衍射特性 ,得到了两者具有相同的失调衍射积分表达式 ,表明两者具有等效性 ,从中提出了失调分数傅里叶变换新概念 .
Based on the misaligned diffraction integral formula for misaligned optical systems, the diffraction for misaligned Lohmann's fractional Fourier transformation system and quasi-asymmetrically inhomogeneous medium are analysed, respectively. It is found that there exist similar expressions of misaligned diffraction integral formula and they are essentially equivalent. And also, a new concept of misaligned fractional Fourier transform is put forward.
