| 摘 要： | 在制作付里叶计算全息过程中，加入适当的二次位相因子，使此种全息图在相干光照明下就可预定的位置上只再现一个像，省略了过去丙现此种计算全息图必要的付里叶透镜，并且使两个互为共轭像分离，从而拓宽了此种计算全息的应用领域，实验结果与理论分析相符。

| Abstract: | A new type of Computer-generated Fourier Transform Hologram(CGFTH) with the ability of self-focusing is described in this paper.A suitable quadratic phase factor is added to the CGFTH.So that there is no need of Fourier lens in reconstruction process. In addition to the reconstruction image,the conjugate image would be recomstructed in another plane.Expreimental results are conformed with the theoretical analysis. |
