| Abstract: | Combining fractional Fourier-domain filtering with optical imaging,a two cascade fractional Fourier transform(FRFT) optical imaging system with filtering aperture is proposed,which is based on Lohmann I single-lens system.Firstly,the basic theory of the FRFT optical imaging combined with the fractional Fourier-domain filtering is discussed according to the relation between FRFT and Fresnel diffraction as well as fractional additivity of FRFT.Then,imaging performance for distant objects is discussed in terms... |
