WebThe input plane is one focal length in front of Lens 1 while the output plane is located one focal length after Lens 2. In between the two lenses, we have the Fourier plane. Here is where we have the Fourier transformation of the object placed at the output plane. The magnification is found to be equal to −f2∕f1.
