摘　　要：The calculation of light diffraction is of great importance for many essential optical applications,including optical lithography,optical tweezers,and super-resolution imaging,and is a research topic that has been extensively studied over the past few decades.Because both scalar and vector diffraction can be formulated as Fourier transforms,the standard method is to use the fast Fourier transform(FFT)algorithm.However,the use of the FFT requires a fixed sampling relation between the discretization of the input field and that of the output field.For the vectorial case,this requirement often causes a significant waste of computational resources,which hinders real-time applications.
