  1. 假彩色编码分数傅里叶变换彩虹全息图

    Pseudo Color Coding Fractional Fourier Transform Rainbow Hologram

  2. 提出了假彩色编码分数傅里叶变换彩虹全息图,并对其再现像的位置、大小、编码色的设计进行了讨论。采用空间滤波合成狭缝彩虹全息术对二维透射物进行假彩色编码。

    A pseudo color coding fractional Fourier transform rainbow hologram is presented in this paper . Spatial filtered pseudocolor encoding of holographic image for two - dimensional transparent object by rainbow holography with synthesized slit is proposed .
