Multiple Fractional Fourier Transform Hologram Recording with Holographic Lens

提出一种用全息透镜记录多重分数傅里叶变换全息图的新方法 ,它能在三维空间不同位置和不同方向上分别再现所记录的多个物体的图象。分析了利用全息透镜记录多重分数傅里叶变换全息图的原理及特点 ,制作了多重分数傅里叶变换全息图 ,并获得了满意的再现结果。

A new method of recording multiple fractional Fourier transform hologram with holographic lens is presented. With this method, images of several recorded objects can be reconstructed in different positions and directions in three dimension space. The theory and characteristics of the multiple fractional Fourier transform hologram recorded with holographic lens are analyzed. A multiple fractional Fourier transform hologram is fabricated and satisfying reconstruction results are obtained.
