摘　　要：提出了用全息透镜实现分数傅里叶变换，讨论了用全息透镜作为分数傅里叶变换元件的条件．用全息透镜来实现分数傅立叶变换，能更好地满足分数傅立叶变换对透镜的焦距变化要求．Implementation of fractional Fourier transformation(FRT) using holographic lens is presented in this paper and the conditions for using holographic lens as a transform element are discussed.The FRT is realized and it is very convenient for holographic lens to solve the problem of focal length changing which is demanded in FRT.
