摘要
在计算全息中 ,对物的频谱加入二次位相因子以后 ,其再现像具有双通道自成像的特性 ,可以方便地演示两个物或同一物的像的变化 ,文中给出了相应的原理和实验结果。
When quadratic phase factors are added into computer generated hologram(CGH),its reconstructed image will have the characters of two channel and self imaging.This CGH is able to conveniently display the change of images of two objects or one object.The Theoretical statement and experimental result are given.
