Based on the theory of fractional Fourier transform and one of its very important parameter, fractional order, the relationship between FRT and Fresnel diffraction are deduced and analyzed. The fractional Fourier transform hologram reconstructed with the Lohmann Ⅰ FRT system is presented and its computer simulation and digital reconstruction are realized. It is shown that FRT is an ideal tool to describe Fresnel diffraction,and the FRTH can record information on the object and the system at the same time,which extends the application areas of FRT and holography.
