In this research, with the incorporation of propagation method concepts of the angular spectrum, and considering the effect produced by the finite apertures of a transforming lens/cemented doublet spherical lens on the amplitude distribution of the diffracted electric field which influences on it, produced by an extended object illuminated with plane waves; the diffraction mathematical model of the Fourier transform of the maximumspatial frequencies was obtained.The experimental results are presented; they are based on diffraction pattern images in intensity distribution engraving in specific conditions through the photographic method and using rectangular geometry apertures as diffractor objects
