A new optical image encryption method based on anamorphic fractional Fourier transform (FRT) and phase-shifting interferometry (PSI) is proposed in this paper. The input two-dimensional image to be encrypted is anamorphic fractional Fourier transformed with different orders in the two orthogonal dir
