Abstract

A pseudo color codingfractional Fourier transform rainbow hologram is presented in this paper. Based on itscharacteristics that the coding color relates not only to the position of slit, but alsoto the fractional order of recording and reconstruction system, a new anti-counterfeitingholography is established.
