Pseudo Color Coding Fractional Fourier Transform Rainbow Hologram

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。基于再现像的位置、大小与记录系统分数阶有关 ,其编码颜色既与狭缝位置又与记录系统和再现系统的分数阶有关的特性 ,可建立一种新的防伪全息术。

A pseudo color coding fractional Fourier transform rainbow hologram was presented as a new kind of holography. Based on its characteristics that the coding color relates not only to the position of slit, but also to the fractional order of recording and reconstruction system, a new anti-counterfeiting holography was established. The recording and reconstruction system was described and the reconstruction results were reported.
